Statistics, probability, basketball foul shots

  1. Jul 6, 2011 #1
    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

    (answer posted below)

    3. The attempt at a solution

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

    Try using the binomial distribution.

    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%.
