4.100 No Time for Vegetables In a survey conducted by Ipsos Canada, 41% Canadians say that because of their busy lifestyles, they find it hard to prepare and eat enough vegetables. Suppose you had conducted your own telephone survey at the same time. You randomly called people and asked them whether they find time to eat vegetables. Assume that the percentage given in the Ipsos Survey can be taken to approximate the percentage of all adult Canadians who find time to eat vegetables.

a. Find the probability for X, the number of calls until you find the first person who does not find time to eat vegetables.

b. What problems might arise as you randomly call people and ask them to take part in your survey? How would this affect the reliability of the prob- abilities calculated in part a?
