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

Probability=number of specific outcomes / total number of possible outcomes.

Probability of two events occurring is P(1)*P(2)

In this case:

P(BandE)=(3/12)(5/10)=15/120=1/8

P(BandE)=1/8 (12.5%)
