Answer 1

The expected number of red balls in Bowl A can be estimated by finding the ratio of red balls to total balls and then multiplying by 500. Let's say the ratio is 3 red balls to 5 total balls (3/5).

Expected number of red balls in Bowl A = (3/5) * 500 = 300
Expected number of white balls in Bowl A = 500 - 300 = 200

The estimated difference in the expected number of red and white balls in Bowl A is:
300 (red) - 200 (white) = 100

Therefore, the estimated difference in the expected number of red and white balls in Bowl A is 100.
