To calculate the probability of randomly selecting a person who will vote for candidate 1 or 2, we need to add up the number of supporters for candidate 1 and candidate 2 and divide it by the total number of registered voters surveyed.
Total number of supporters for candidate 1 and candidate 2 = 250 (candidate 1) + 1250 (candidate 2) = 1500
Total number of registered voters surveyed = 2500
Therefore, the probability of randomly selecting a person who will vote for candidate 1 or 2 is:
1500 / 2500 = 0.6
So, the probability is 0.6 or 60%.
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.
