In December 2008, 500 men and 500 women were surveyed by Omnitel about their opinion on whether federal government bailout money should be used to help homeowners in default. The number giving each response is shown below.
Response | Men | Women |
Yes | 195 | 235 |
No | 290 | 220 |
Not sure | 15 | 45 |
(a) If a person who participated in the survey is selected at random, what is the probability that he or she answered no?
(b) What is the probability that the person is a man who answered either yes or no?
(c) Based on the data from the survey, if you had stopped a random woman on the street in December 2008 and asked her opinion, what is the probability that she would have said that bailout money should not be used to help homeowners in default?
