Suppose that the probability of a fatal accident in a given year is 0.0000004. A binomial probability distribution for = n 11,000,000 and p = 0.0000004 with x = 0 to 12 is shown. P(x) 0.20 0.25 0.012 0,054 0.119 0.192 0.174 0.169 0.124 0.078 0.043 0.021 0 1 2 3 4 5 6 7 8 9 10 11 12 Number of accidents 600'0 0.004 100'0 What is the probability that there will be

(a) 4 fatal accidents in a year?

(b) 10 fatal accidents?

(c) between 1 and 5, inclusive? n
