2) How do you find the percent of a number?

3) How do you find the experimental probability of a compound event?

2) you first convert the percentage number to a decimal. This process is the reverse of what you did earlier. You divide your percentage by 100. So, 40% would be 40 divided by 100

3) finding the sum of the probabilities of the individual events and, if necessary, removing any overlapping probabilities. An exclusive compound event is one in which the multiple events do not overlap. In mathematical terms: P (C) = P (A) + P (B).
