To calculate the probability of randomly selecting a person who will vote for candidate one or two, we need to add the number of people who will vote for candidate one to the number of people who will vote for candidate two, and then divide by the total number of registered voters surveyed.
From the table, we see that 700 people will vote for candidate one and 800 people will vote for candidate two.
Therefore, the total number of people voting for candidate one or two is 700 + 800 = 1500.
The total number of registered voters surveyed is 2500.
Thus, the probability of randomly selecting a person who will vote for candidate one or two is:
1500 / 2500 = 0.6
Therefore, the probability is 0.6 or 60%.
