How often is the probability of the complement of an event less than the probability of the event itself?
It depends on the events.
The answer is 0.5*(Total number of events - number of events with probability = 0.5)
That is, discount all events such that their probability (and that of their complement) is exactly a half.
Then half the remaining events will have probabilities that are greater than their complement's.

How can you state and illustrate the addition multiplication Theorem of Probability?
Addition Theorem The addition rule is a result used to determine the probability that event A or event B occurs or both occur. ; The result is often written as follows, using set notation: : ; where: : P(A) = probability that event A occurs : P(B) = probability that event B occurs : = probability that event A or event B occurs : = probability that event A and event B both occur ; For mutually exclusive events, that is events which cannot occur together: : = 0 ; The addition rule therefore reduces to : = P(A) + P(B) ; For independent events, that is events which have no influence on each other: : ; The addition rule therefore reduces to : ; Example ; Suppose we wish to find the probability of drawing either a king or a spade in a single draw from a pack of 52 playing cards. ; We define the events A = 'draw a king' and B = 'draw a spade' ; Since there are 4 kings in the pack and 13 spades, but 1 card is both a king and a spade, we have: : = 4/52 + 13/52 - 1/52 = 16/52 ; So, the probability of drawing either a king or a spade is 16/52 (= 4/13).MultiplicationTheorem The multiplication rule is a result used to determine the probability that two events, A and B, both occur. The multiplication rule follows from the definition of conditional probability. ; The result is often written as follows, using set notation: : ; where: : P(A) = probability that event A occurs : P(B) = probability that event B occurs : = probability that event A and event B occur : P(A | B) = the conditional probability that event A occurs given that event B has occurred already : P(B | A) = the conditional probability that event B occurs given that event A has occurred already ; For independent events, that is events which have no influence on one another, the rule simplifies to: : ; That is, the probability of the joint events A and B is equal to the product of the individual probabilities for the two events.
Is probability a noun?
Yes, the word 'probability' is a noun, a singular, common, abstract noun; a word for the chance that something will happen; something that has a chance of happening; a measure of how often a particular event will happen; a word for a concept; a word for a thing.
What is the probability of rolling a 4 5 times in a row on 1 die?
If you roll the die often enough, the event is a certainty and so the probability is 1. If you consider only the first 5 rolls, the answer is (1/6)5 = 1/7776 = 0.000129 approx.
What is probability in risk management?
A probability is an estimation of how likely an event is to happen. Looking at various statistics one can give an "event" (say a river flooding an area) a score of how often in a set "period" (of say 100 years) the event will happen. - 1in 100 , 10 in 100, etc. This is the likelihood of this risk and will help inform decisions as to how to prioritise this risk (among many others that may affect people or a project).
What is the probability of not rolling a sum of 2 with two fair dice?
If you roll them often enough then the probability is 0. For just one roll, the probability is 35/36.
What is the describing of the complementary event and find its probability?
Suppose there is an event A and the probability of A happening is Pr(A). Then the complementary event is that A does not happen or that "not-A" happens: this is often denoted by A'.Then Pr(A') = 1 - Pr(A).Suppose there is an event A and the probability of A happening is Pr(A). Then the complementary event is that A does not happen or that "not-A" happens: this is often denoted by A'.Then Pr(A') = 1 - Pr(A).Suppose there is an event A and the probability of A happening is Pr(A).

What is the probability of rolling a number that is divisible by two on a six sided die?
If the die is rolled often enough, the event is a certainty - probability = 1. For a single roll, the probability is 1/2.
What is it when all outcomes are different from the favorable outcome?
When all outcomes are different from the favorable outcome, it typically refers to a situation where the event of interest does not occur, resulting in a complete failure to achieve the desired result. This scenario is often analyzed in probability, where it highlights the concept of complementary events. Essentially, the favorable outcome is one distinct possibility, while all other outcomes represent the complement of that event. In statistical terms, this situation illustrates a zero probability for the favorable outcome.

Is 1 in 300000000 rare?
In statistical terms, an event with a probability of 1 in 300,000,000 is considered rare. This means that out of a population of 300 million, only one individual is expected to experience this event. The rarity of an event is often determined by comparing its probability to the total population or sample size. In this case, the likelihood of the event occurring is extremely low, making it rare.
What is the Difference between fuzzy logic and probability?
The difference between probability and fuzzy logic is clear when we consider the underlying concept that each attempts to model. Probability is concerned with the undecidability in the outcome of clearly defined and randomly occurring events, while fuzzy logic is concerned with the ambiguity or undecidability inherent in the description of the event itself. Fuzziness is often expressed as ambiguity rather than imprecision or uncertainty and remains a characteristic of perception as well as concept.
Likelihood that something will happen?
The likelihood that something will happen refers to the probability or chance of that event occurring. It is often quantified on a scale from 0 (impossible) to 1 (certain). The higher the likelihood, the greater the probability of the event occurring.

Is probability an abstract noun?
No, probability is not an abstract noun. It is a concept in mathematics that quantifies the likelihood of a specific event occurring. Abstract nouns refer to ideas, qualities, or states rather than tangible objects, whereas probability is a measurable quantity that can be calculated and analyzed using mathematical formulas and tools.
Expression of possible loss adverse outcome or negative consequence in terms of probability and severity?
Loss adverse outcomes can be expressed through a risk assessment framework that considers both the probability of an event occurring and the severity of its consequences. Probability refers to the likelihood of an adverse event happening, often quantified as a percentage or ratio. Severity measures the potential impact of the event, which can range from minor disruptions to catastrophic failures. By combining these two dimensions, organizations can prioritize risks and develop mitigation strategies effectively.
What Term describes the chance that an event should happen under perfect circumstances?
The term that describes the chance that an event should happen under perfect circumstances is "theoretical probability." This probability is calculated based on the possible outcomes of an event in an ideal scenario, without any external influences or biases affecting the results. It is often expressed as a ratio of the number of favorable outcomes to the total number of possible outcomes.
