help with my statistics and probability HW

In a recent year, the mean number of strokes per hole for a famous golfer was approximately 3.7. 2 (a) Find the variance and standard deviation using the fact that the variance of a Poisson distribution is o- = H- (b) How likely is this golfer to play an 18-hole round and have more than 72 strokes? (a) The variance is 3.7 . (Round to the nearest tenth as needed.) The standard deviation is 1.9 strokes. (Round to the nearest tenth as needed.) (b) The probability of more than 72 strokes in an 18-hole round is (Round to the nearest thousandth as needed.)
