Given that this person voted in the local election, what is the probability that he or she is:

The first step to solve this problem is finding the fraction of voters that participated in the local election, that is, question d.

(d) What fraction of voters participated in the local election?

This is the sum of 35% of 46%, 62% of 30%, 58% of 24%. So:

48.62% of voters participated in the local election.

(a) an Independent

46% of the people are independent, and 35% of them voted.

So the probability that the person is an independent, given that she voted is:

Given that this person voted in the local election, there is a 33.11% proabability that he or she is an Independent.
