Answer 1

To find the probability that a randomly selected person from this group is conservative given they have attended college, we need to look at the number of conservatives who have attended college, which is 15, and divide it by the total number of people who have attended college, which is 18 + 12 + 15 = 45.

So, the probability that a randomly selected person from this group is conservative given they have attended college is:
15/45 = 1/3 or 0.33 or 33%
