Basic Math

For drivers aged 20-24 there is a 34% chance of having a caraccident in a one year period (based on data from the NationalSafety Council).
(a) Based on this data, in a group of 11 randomly selected driversaged 20-24, find the probability that at least 2 of them will havea car accident in the next year.
(b) In a group of 260 drivers aged 20-24, find the mean number ofdrivers who will have a car accident in the next year.
(c) In a group of 260 drivers aged 20-24, find the standarddeviation of the number of drivers who will have a car accident inthe next year.
(d) Suppose that a group of 260 drivers aged 20-24 are randomlyselected, and 106 of them have had a car accident in the last year.Is this a significantly high number that would perhaps suggest thatthe given percentage of drivers aged 20-24 that have a car accidentin a one year period (i.e., 34%) is not correct?
