The probability is 1 in 4,000,000 that a single auto trip in the united states will result in a fatality. Over a liftime, an average u.s. driver takes 50,000 trips. What is the probability of a fatal accident over a lifetime?
1 / 4,000,000 = 0.00000025 0.00000025/50000 = 0.000000000005
------
Binomial with n = 50,000 and p = 1/4million
The result of each trip is independent of every other trip.
------
P(x = 1) = (50,000,1/4000000,1) = 50,000*(1/4000000)^1*1 = 0.0125
