In 1981, the wall street journal notes that hang gliding can be dangerous. Of the estimates 36000 hang -gliding enthusiasts in the united states, 29 were killed last year in hang gliding accidents and, it is estimates, thousands more are injured. Suppose that a hang glider pilot randomly selected from among all hang glider pilots has probability 0.0006 of being killed in any one year. If there are 40,000 pilots next year:
a. What kind of distribution do we have here?
b. What is the expected number of fatalities?
c. What is the standard deviation of the number Y of fatalities?
d. Is it likely that the number of fatalities would exceed 40?( You can use Chebyshev's)
