a) 3/26 is that correct

In one town, 336% of all voters are Democrats. If two voters are randomly selected for a survey find the probability that they are both Democrats.

c) 0.690

a) No. There are 12 face cards (4 x 3) and 10 spades that are not face cards . The probability you get one or the other is 22/52.

b) How can 336% of voters be Democrats? Do you mean 33.6%? If so, the answer is (0.336)^2

If the number of voters is very large, the probability of getting the same party twice in a row is the square of whatever the probability is for a single selection.
