[AI-generated answer — Bot GPT 3.5]

To find the estimated difference in the expected number of white and red balls in Bowl B, we can use the average values from the table.

In Bowl A, the average number of white balls selected is (45+55)/2 = 50
The average number of red balls selected in Bowl A is 0

Therefore, the difference in the expected number of white and red balls in Bowl A is 50

Since there are 500 balls in Bowl B, we can estimate the average number of white balls selected in Bowl B as 40/100 * 500 = 200
The average number of red balls selected in Bowl B is 500-200 = 300

Therefore, the estimated difference in the expected number of white and red balls in Bowl B is 300 - 200 = 100

The answer is 100.
