I'm a little unshure on how to solve this problem please help.
The clayton Automobile Insurance Company only insures drivers that are 18 years of age. It has been determined that the probability that an 18 year old driver has an accident in a one year span is 24.65%. If the company insures twenty 18 year old drivers for a one year contract, determine the following.
a) What is the probability that none of the drivers have an accident during their contract?
b) What is the probability that at least 2 drivers have an accident during their contract?
