Amusement Ride Safety. Approximately 297 million guests visit the 400 American amusement parks annually and take 1.7 billion safe rides. The National Safety Council publishes a report titled Fixed-Site Amusement Ride Injury Survey for the International Association of Amusement Parks and Attractions. The number of injuries per million patron-rides, X, has a Poisson distribution with parameter 0.8. In one million patron-rides, what is the probability that there are

a. no injuries?

b. more than two injuries?

c. Construct a table of probabilities for the random variable X. Compute the probabilities until they are zero to three decimal places.

d. Draw a histogram of the probabilities in part (c).
