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.
(I'm confused so pls helpðŸ˜)

To provide assistance with understanding the table, please provide the information or the table that you are referring to so I can help clarify the results for you.
Sorry~
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?

To calculate the probability of randomly selecting a person who will vote for Candidate 1 or Candidate 2, you need to add the number of voters for Candidate 1 and Candidate 2, then divide by the total number of voters surveyed.
Number of voters for Candidate 1: 250
Number of voters for Candidate 2: 1250
Total number of voters surveyed: 2500
Probability = (Number of voters for Candidate 1 + Number of voters for Candidate 2) / Total number of voters surveyed
Probability = (250 + 1250) / 2500
Probability = 1500 / 2500
Probability = 0.6
Therefore, the probability of randomly selecting a person who will vote for Candidate 1 or Candidate 2 is 0.6 or 60%.
Number of voters for Candidate 1: 250
Number of voters for Candidate 2: 1250
Total number of voters surveyed: 2500
Probability = (Number of voters for Candidate 1 + Number of voters for Candidate 2) / Total number of voters surveyed
Probability = (250 + 1250) / 2500
Probability = 1500 / 2500
Probability = 0.6
Therefore, the probability of randomly selecting a person who will vote for Candidate 1 or Candidate 2 is 0.6 or 60%.
Ok thx
I looked through other people's answers for the next question, and you didn't get it right for any of them it seems, but thanks for this one

If 1,000 more voters are surveyed, how many of them will likely prefer
Candidate 3 or 4? Explain the answer.
Candidate 3 or 4? Explain the answer.
To determine how many of the additional voters are likely to prefer Candidate 3 or 4, we can first calculate the proportion of voters who preferred Candidate 3 or 4 in the initial survey and then apply this proportion to the additional 1,000 voters.
In the initial survey:
Number of voters for Candidate 3: 450
Number of voters for Candidate 4: 550
Total number of voters surveyed: 2500
Total number of voters for Candidate 3 or 4: 450 + 550 = 1000
Proportion of voters for Candidate 3 or 4 in the initial survey: (450 + 550) / 2500 = 1000 / 2500 = 0.4
Now, if 1,000 more voters are surveyed, we can estimate how many of them are likely to prefer Candidate 3 or 4 by multiplying the proportion calculated above by the additional 1,000 voters:
Number of voters likely to prefer Candidate 3 or 4 from the additional 1,000 voters = 0.4 * 1000
Number of voters likely to prefer Candidate 3 or 4 from the additional 1,000 voters = 400
Therefore, it can be estimated that 400 of the additional 1,000 voters will likely prefer Candidate 3 or 4. This estimation is based on the proportion of voters for Candidate 3 or 4 in the initial survey.
In the initial survey:
Number of voters for Candidate 3: 450
Number of voters for Candidate 4: 550
Total number of voters surveyed: 2500
Total number of voters for Candidate 3 or 4: 450 + 550 = 1000
Proportion of voters for Candidate 3 or 4 in the initial survey: (450 + 550) / 2500 = 1000 / 2500 = 0.4
Now, if 1,000 more voters are surveyed, we can estimate how many of them are likely to prefer Candidate 3 or 4 by multiplying the proportion calculated above by the additional 1,000 voters:
Number of voters likely to prefer Candidate 3 or 4 from the additional 1,000 voters = 0.4 * 1000
Number of voters likely to prefer Candidate 3 or 4 from the additional 1,000 voters = 400
Therefore, it can be estimated that 400 of the additional 1,000 voters will likely prefer Candidate 3 or 4. This estimation is based on the proportion of voters for Candidate 3 or 4 in the initial survey.
I don't think that's correct, could you please double check and make sure.
Apologies for the confusion in the previous response. Let's recalculate the number of voters who are likely to prefer Candidate 3 or 4 from the additional 1,000 voters.
In the initial survey:
Number of voters for Candidate 3: 450
Number of voters for Candidate 4: 550
Total number of voters surveyed: 2500
Total number of voters for Candidate 3 or 4: 450 + 550 = 1000
Proportion of voters for Candidate 3 or 4 in the initial survey: (450 + 550) / 2500 = 1000 / 2500 = 0.4
Now, if 1,000 more voters are surveyed:
Additional 1,000 voters
Expected number of voters likely to prefer Candidate 3 or 4 from the additional 1,000 voters = Proportion of voters for Candidate 3 or 4 * Additional voters
Expected number = 0.4 * 1000 = 400
Therefore, it is expected that 400 of the additional 1,000 voters will likely prefer Candidate 3 or 4 based on the proportion from the initial survey.
In the initial survey:
Number of voters for Candidate 3: 450
Number of voters for Candidate 4: 550
Total number of voters surveyed: 2500
Total number of voters for Candidate 3 or 4: 450 + 550 = 1000
Proportion of voters for Candidate 3 or 4 in the initial survey: (450 + 550) / 2500 = 1000 / 2500 = 0.4
Now, if 1,000 more voters are surveyed:
Additional 1,000 voters
Expected number of voters likely to prefer Candidate 3 or 4 from the additional 1,000 voters = Proportion of voters for Candidate 3 or 4 * Additional voters
Expected number = 0.4 * 1000 = 400
Therefore, it is expected that 400 of the additional 1,000 voters will likely prefer Candidate 3 or 4 based on the proportion from the initial survey.
Ok... this better be correct.
