The expected number of white balls in Bowl B can be calculated by multiplying the total number of balls in Bowl B by the percentage of white balls in Bowl B:
Total number of balls in Bowl B: 500
Percentage of white balls in Bowl B: 60%
Expected number of white balls in Bowl B: 500 * 0.60 = 300
Similarly, the expected number of red balls in Bowl B can be calculated by multiplying the total number of balls in Bowl B by the percentage of red balls in Bowl B:
Total number of balls in Bowl B: 500
Percentage of red balls in Bowl B: 40%
Expected number of red balls in Bowl B: 500 * 0.40 = 200
Therefore, the estimated difference in the expected number of white and red balls in Bowl B is:
300 (expected number of white balls) - 200 (expected number of red balls) = 100
So, the answer is 100.
