Driving under the Influence Among 21-to 25-years-olds, 29% say they have driven while under the influence of alcohol. Suppose that three 21-to 25-years-olds are selected at random (12 Points) 

a. What is the probability that all three have driven while under the influence of alcohol? 

b. What is the probability that at least one has not driven while under the influence of alcohol? 

c. What is the probability that none of the three had driven while under the influence of alcohol? 

d. What is the probability that at least one has driven while under the influence of alcohol? 

Using a class width of 64, give the upper and lower limits for 9 classes, starting with a lower limit of 27 for the first class.
