The estimated difference in the expected number of white and red balls in Bowl B can be calculated by finding the difference between the percentages of white and red balls selected from Bowl B.
From the table, Bowl B has 60 white balls (60/500 = 12%) and 40 red balls (40/500 = 8%). The difference between 12% and 8% is 4%.
Since there are 500 balls in Bowl B, the estimated difference in the expected number of white and red balls in Bowl B is 4% of 500 which is 20.
Therefore, the answer is 50.
Use the table to answer the question.
Number of White Balls Selected Number of Red Balls Selected
Bowl A 45 55
Bowl B 60 40
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?
