Best Answer

The probability of event A is the number of ways event A can occur divided by the total number of possible outcomes. For example, the number of ways you can role a single die is 6, the number of ways to get an even number (2,4, or 6) is 3. So the probability of an even number is 3/6 or .5

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 difference between theoretical probability and experimental probability?

The difference between experimental probability and theoretical probability is that experimental probability is the probability determined in practice. Theoretical probability is the probability that should happen. For example, the theoretical probability of getting any single number on a number cube is one sixth. But maybe you roll it twice and get a four both times. That would be an example of experimental probability.
