A high school baseball player has a 0.193 batting average. In one game, he gets 7 at bats. What is the probability he will get at least 2 hits in the game?

  • Probability and Statistics -

    this is a binomial problem

    probability of hit (h) = .193

    probability of no hit (n) = 1 - .193 = .807

    at least 2 means not zero and not one

    (n + h)^7 = n^7 + 7 n^6 h...

    p(h ≥ 2) = .807^7 + (7 * .807^6 * .193)
