Question

Bob is a high school basketball player. he is a 70% free-throw shooter (his probability of making a free throw is 0.70). what is the probability that bob makes his first free throw on his second shot?

Answer 1

Probability he doesn't make a free shot = 10/10 - 7/10 = 3/10
Doesn't first time, does second time, so...
3/10 x 7/10 = 21/100
