A professional baseball player has a batting average of 0.286, which is his probability of getting a hit in an official at-bat. Let X be the number of hits he gets in 10 official at-bats so that X is a binomial random variable with n = 10 and p = 0.286. Find P(X = 3), showing how to use the formula as part of your work.

Option #1: Batting The batting average of a baseball player is the number of “hits” divided by the number of “at-bats.” Recently, a certain major league player’s at-bats and corresponding hits were recorded for 200 consecutive games. The consecutive games span more than one season. Since each game is different, the number of at-bats and hits both vary. For this particular player, there were from zero to five at-bats. Thus, one can sort the 200 games into six categories: 0...
