There are two main methods: the empirical method and the theoretical method.
Suppose you want the probability of throwing a 6 on one roll of a die.
Empirical method: Throw the die lots and lots of times and count the total number of throws as well as the number of throws that result in a 6. The probability of throwing a six is the number of times you get a 6 divided by the total number of throws.
Theoretical method: A die is a cube with six equal faces. Assuming the die is fair, each face has an equal probability of turning up. There are no other outcomes possible (the probability of the die ending up on an edge or a vertex are assumed to be zero). So, there are six outcome, and each equally probable, so that each has a probability of 1/6.

How do you find the probability of the complement of an event?
The probability of the complement of an event, i.e. of the event not happening, is 1 minus the probability of the event.
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.
What is the probability of an event b that 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.
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 not occurring?
Well, isn't that just a happy little question! When we talk about the probability of an event not occurring, we're looking at the complement of that event. To find this probability, we simply subtract the probability of the event happening from 1. Remember, there are always happy accidents in math, so don't be afraid to explore and make mistakes along the way!
