In a school baskeball championship players must make 10 free throws and the player who takes the lowest number of shots
wins the competetions. In a past competetion a student made 90% of his shots. Assuming he performs similarly that is 90% chance of making hi sshots how likely will he make all of his first 10 shots

^The chance that he makes first shot is 90% or 0.9. The chances that he makes 2 shots in 2 is 0.9*0.9, 3 in 3 0.9*0.9*0.9, ....10 in 10 = 0.9^10

Hi rsx0005,

whenever there is "and" in the question we should multiply probabilities, here he has to make the 1st and 2nd and 3rd and ...10th shot, and the probability that he will make any given shot is 90/100 = 0.9, so 0.9*0.9*0.9 (10 times) resulting in 0.9^10
