The expected number of white balls selected from Bowl B can be calculated as (60/100)*500 = 300 white balls.
Similarly, the expected number of red balls selected from Bowl B can be calculated as (40/100)*500 = 200 red balls.
The estimated difference in the expected number of white and red balls in Bowl B is 300 - 200 = 100.
Therefore, the answer is b. 100.
Number of white balls selected Number of red balls selected
Bowl A 45 55
Bowl B 60 40
Bowl a and bowl 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.
a. 300
b. 100
c. 200
