What is the equation used to determine probability in what ways can probability be expressed?
Probability = number of times an event is expected to happen / number of opportunities for an event to happen It can be expressed as a percentage or a fraction.
What is complementary rule?
The complementary rule is a principle in probability theory stating that the probability of an event not occurring is equal to one minus the probability of the event occurring. Mathematically, it can be expressed as P(A') = 1 - P(A), where P(A') is the probability of the complement of event A, and P(A) is the probability of event A. This rule is useful for calculating probabilities when it's easier to determine the likelihood of an event not happening rather than the event itself.
What is the multiplication rule?
States that to determine a probability, we multiply the probability of one event by the probability of the other event. Ex: Probability that two coins will land face heads up is 1/2 x 1/2 = 1/4 .
What type of probability used sample spaces to determine the numerical probability that an event will occur?
Discrete probability. It helps if the all the outcomes in the sample space are equally probable but that is not a necessity.
The probability that an event will occur is 0.2. what is the probability that the event will not occur?
The probability that an event will not occur is calculated by subtracting the probability of the event occurring from 1. Given that the probability of the event occurring is 0.2, the probability that it will not occur is 1 - 0.2 = 0.8. Thus, there is an 80% chance that the event will not occur.
What is the definition of theoretical probability?
Theoretical probability is the probability of an event when all outcomes are equally likely. With theoretical probability, you determine the probability by dividing the number of ways the event can occur by the total number of equally likely outcomes.

Probability = number of times an event is expected to happen / number of opportunities for an event to happen It can be expressed as a percentage or a fraction.

What type of probability is when it uses sample spaces to determine the numerical probalitiy that an event will happen?
Classical Probability!
What type of probability uses a knowledge of sample spaces as opposed to experiments to determine the numerical probability that an event will occur?
Theoretical probability.
What help determine the chance that something will occur?
Probability is a field of mathematics that helps determine the likelihood of something happening.
A probability of 1 means an event is?
100% going to occur.
Which two factors determine the risk level?
Probability of the occurrence and severity of the event.
What is the multiplication rule?
States that to determine a probability, we multiply the probability of one event by the probability of the other event. Ex: Probability that two coins will land face heads up is 1/2 x 1/2 = 1/4 .
What is the probability of an event b that impossible?

What is the probablity of an event that is impossible?
The probability of an impossible event is 0.The probability of an impossible event is 0.The probability of an impossible event is 0.The probability of an impossible event is 0.
What type of probability used sample spaces to determine the numerical probability that an event will occur?
