## statistics, probability, basketball foul shots

1. The problem statement, all variables and given/known data

Records show that 72% of basketball foul shots attempted are successfully made during practice. Today, each of the 10 members of the team gets a practice shot. What is the probability that at least 8 team members make the shot successfully?

2. Relevant equations

3. The attempt at a solution

(8/10 * .72) + (9/10 * .72) + (10/10 * .72) = 1.944

 Consider the rule for figuring 'AND' probabilities. For example, what is the probability that two coin flips in a row will both be tails? 0.5 X 0.5 = 0.25 = 25%. So there is also a 25% chance both will be tails. Since all the probabilities must add to 100%, the chance of one flip being heads and the other tails is 50%.
