Question

Frank is conducting an experiment. He has one bag of different colored, same-size chips and one bag of ten same-size chips numbered 1-10. In the first bag there are 4 blue chips, 5 red chips, and 3 black chips. If he pulls one chip out of each bag, what is the probability that he will pull a black chip and an even number?

Answer 1

The probability of choosing a black chip is 3/12 or 1/4. The probability of choosing an even number chip is 5/10 or 1/2. To find the compound probability, you multiply the two probabilities and you get 1/8.
