The probability of a given event is a measure of the likelihood that the event occurs. Probability, itself, is the branch of mathematics which studies how such a measure can be calculated or estimated and of how the probabilities of events can be combined.

Probability is the chance that something will happen, there are two kinds of probability, theoretical and experimental. Theoretical probability is based on a sample or repeated trials of the experiment. The experimental probability is given by:

OR

Theoretical probability:

When all outcomes are equally likely the theoretical probability of an event is the ratio of the number of favorable outcomes to the number of possible outcomes.

In math the definition for probability is: a numerical measure of the likelihood of occurrence of an event. EX. You want to take a blue marble from a bag containing 1 blue marble and 5 red marbles is 1 in 6 or 16.667%.
Probability is the likelihood that something will happen.
The likelihood that something will happen
Probability is a number that describes how likely it is that a certain event will occur.

What does it mean to find the compliment of the probability of an event?

The complement (not compliment) of the probability of event A is 1 minus the probability of A: that is, it is the probability of A not happening or "not-A" happening.The complement (not compliment) of the probability of event A is 1 minus the probability of A: that is, it is the probability of A not happening or "not-A" happening.The complement (not compliment) of the probability of event A is 1 minus the probability of A: that is, it is the probability of A not happening or "not-A" happening.The complement (not compliment) of the probability of event A is 1 minus the probability of A: that is, it is the probability of A not happening or "not-A" happening.

If the odds against an event are 9.8 find the probability that the event will occur?

Odds against A = Probabillity against A / Probability for A Odds against A = (1 - Probabillity for A) / Probability for A 9.8 = (1 - Probabillity for A) / Probability for A 9.8 * Probability for A = 1 - Probability for A 10.8 * Probability for A = 1 Probability for A = 1 / 10.8 Probability for A = 0.0926


What is the probability of an event occurring to the probability that it will not occur?
