It has been reported that last year 25% of drivers have fallen
asleep at the wheel. Source: National Sleep Foundation If 100
drivers are selected at random, find the following probabilities:
[4a] Find the probability that at most 27 drivers will say that
they have fallen asleep while driving. [4b] Use [4a] to find the
probability that exactly 27 drivers will say that they have fallen
asleep while driving. [4c] Find the probability that less than 24
drivers will say that they have fallen asleep while driving. [4d]
Use [4a, b, c] to find the probability that between 24 and 27
drivers will say that they have fallen asleep while driving.
