Question

coming election. The table summarizes the results of the survey.
Presidential Candidates Number of Supporters
Candidate 1 250
Candidate 2 1,250
Candidate 3 450
Candidate 4 550
250+1,250+450+550=2,500 so candidate 2 has more supporters


a. What is the probability of randomly selecting a person who will vote for Candidate 1 or 2?

Answer 1

To find the probability of selecting a person who will vote for Candidate 1 or 2, we need to add the number of supporters for Candidate 1 and Candidate 2 and divide it by the total number of supporters.

P(Candidate 1 or 2) = (250 + 1,250) / 2,500
P(Candidate 1 or 2) = 1,500 / 2,500
P(Candidate 1 or 2) = 0.6

Therefore, the probability of randomly selecting a person who will vote for Candidate 1 or 2 is 0.6 or 60%.
