Calculate the probability of no accidents occurring during the current three-month period. c. Find the probability that fewer accidents will occur during the current three-month period than during the last three months. d. Calculate the probability of no more than 12 accidents occurring in a given year. e. Find the probability ofno accidents occurring for a particular year
