There are four presidential candidates in a country. A street survey was conducted asking 2,500 registered voters which candidate they will vote for in the coming election. The table summarizes the results of the survey.
Candidate 1 : 250
Candidate 2 : 1,250
Candidate 3 : 450
Candidate 4 : 550
What is the probability of randomly selecting a person who will vote for
Candidate 1 or 2?
The probability of selecting a person who will vote for Candidate 1 or 2 is the sum of the probabilities of selecting a person who will vote for Candidate 1 and the probability of selecting a person who will vote for Candidate 2.
P(Candidate 1 or 2) = P(Candidate 1) + P(Candidate 2)
= 250/2500 + 1250/2500
= 1500/2500
= 0.6
Therefore, the probability of randomly selecting a person who will vote for Candidate 1 or 2 is 0.6 or 60%.
