Bowls A and B contain a number of white and red balls. Clark repeatedly selected a ball from both bowls and recorded the results in a table. If there are 500 balls in Bowl B, what is the estimated difference in the expected number of white and red balls in Bowl B?
Bowl A : 45, 55
Bowl B : 60, 40
Number of white balls selected : 45, 60
Number of red balls selected : 55, 40

The expected number of white balls in Bowl B can be calculated as (60/100)*500 = 300, and the expected number of red balls in Bowl B can be calculated as (40/100)*500 = 200. Therefore, the estimated difference in the expected number of white and red balls in Bowl B is 300 - 200 = 100.
