Rogers Hornsby has a lifetime batting average of 0.358. Assume that Rogers Hornsby came to bat officially six times every game played. What would be Rogers Hornsby's probability getting at least five hits in a game?
here we have,
proportion, p = 0.358
sample size, n = 6
we know that,
P(X = x) = nCx px (1-p)n-x
Probability of getting at least five hits is,
P(x >=5) = P(X = 5) + P(X = 6)
= 6C5 * 0.358^5 * (1-0.358)^(6-5) + 6C6 * 0.358^6 * (1-0.358)^(6-6)
= 0.02265 + 0.00211
= 0.0248 (Rounded to 4 decimal places)
please revert if any doubts

A baseball player has a batting average (probability of getting on base per time at bat) of 0.215. Based on this: What is the probability that they will get on base more than 6 of the next 15 at bats?
Please use the central limit theorem. 9.14 A baseball player has a batting average of 0.328. Let X be the number of hits the player gets during 20 times at bat. Use the central limit theorem to find the approximate probability P(X<k) for k = 1, 3, 6. Compare with the exact probability for each k. Problem 9.14. The problem assumes that the batter's probability of getting a hit stays constant at p=0.328 while he comes up to bat 20...
