Jim is at the racetrack and has bet on his favorite horse. At post time, the odds in favor of his horse winning
were 5:7.

Mark looked at the statistics for his favorite baseball player, Joe Mauer. Mark looked at seasons when Mauer
played 150 or more games and found that Mauer's probability of hitting a home run in a game is 0.189.
If Mark uses the normal approximation of the binomial distribution, what will be the variance of the
number of home runs Bautista is projected to hit in 150 games? Answer choices are rounded to the tenths
place.
