Refer to the Baseball 2018 data. Compute the mean number of home runs per game. To do this, first find the mean number of home runs per team for 2018. Next, divide this value by 180 (a season comprises 180 games). Then multiply by 2 because there are two teams in each game. Use the Poisson distribution to estimate the number of home runs that will be hit in a game. (Round your answers to 4 decimal places.) a. Find the probability that there are no home runs in a game.

b. Find the probability that there are two home runs in a game. c. Find the probability that there are at least four home runs in a game.
