A probability is a ratio of a fraction in between?
If the outcomes of the trials are equally likely, then (and only then) is it the number of favourable outcomes and the total number of trials.
What is the formula in finding the probability of an event?
If you can enumerate the outcome space into equally likely events, then it is the number of outcomes that are favourable (in which the event occurs) divided by the total number of outcomes.
How do you figure probablity?
Calculating Probabilities for Equally Likely OutcomesStep 1: Count the total number of possible outcomes of an eventStep 2: Count the number of outcomes that represent a success - that is, the number of outcomes that represent the desired result.Step 3: Determine the probability of success by dividing the number of successes by the total number of possible outcomes:
Is there a formula for probability problems?
Yes. The sum of the probabilities of all possible outcomes is equal to one. Given events that are equally likely to happen, the probability that any given outcome occurs will be equal to the number of specified outcomes, divided by the number of all outcomes. If events are not equally likely to happen - let's say that Bent-Nose Bill is holding a lottery - then the probability is considerably different. As Damon Runyan put it, "The race is not always to the swift, nor the battle to the strong, but that's the way to bet"
What is the word for when all outcomes are equally likely it is the ratio of the number of favorable outcomes to the number of possible outcomes it mus be in two words?
fifty-fifty
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.
What in an event is the ratio of the number of favorable outcomes to the number of possible outcomes?
That's the 'probability' of a favorable outcome.but only if the outcomes are equally likely.

How do you fiqure out probability?
The probability of an event is the ratio of the number of equally likely oucomes of a trial which are favourable to that event, and the total number of outcomes.
What is the formula in finding the probability of an event?
If you can enumerate the outcome space into equally likely events, then it is the number of outcomes that are favourable (in which the event occurs) divided by the total number of outcomes.
What is the ratio of the number of ways an event can occur to the total number of possible outcomes?
If each of the ways is equally likely then it is the probability of the event but otherwise it is simply a ratio.

What is probablity ratio?
If the outcomes of a trial or experiment are all equally likely then the probability ratio for a specific event is the ratio of the number of outcomes that are favourable to the event divided by the total number of possible outcomes.

The theoretical probability of a given event is 9 13 explain what each number represents?
The naive answer is that the random experiment (or trial) can be modelled theoretically. This model has 13 equally likely outcomes and that 9 of them are favourable to the event. That is, 9 out of 13 equally likely outcomes involve the event occurring.A slightly more sophisticated explanation is that there are a multiple of 13 equally likely outcomes and the same multiple of 9 are favourable to the event under study. For example, the probability of randomly drawing a non-honour from a regular deck of cards. The total number of possible outcomes is 52 (= 13*4) and the number of favourable outcomes is 36 (= 9*4). The probability, 36/52 has then been simplified to 9/13.This answer still assumes that each individual outcome is equally likely but that is not necessary. The experiment could involve trying to hitting one of two targets: a 2*2 and a 3*3 (in the same square units of length) targets. If anywhere in the two targets has the same probability, then the theoretical probability of hitting the bigger target is 9/(9+4) = 9/13.
What is the equation of probability?
The probability of an event occurring can be found by dividing the number of favorable outcomes (what you want to happen) by the number of possible outcomes number of favorable outcomes probability = _________________________ number of possible outcomes
