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

Question

Bowl A= Amount of White Balls are 25 and amount of red balls are 75
Bowl B= Amount of white balls are 40 and amount of red balls are 60
Answer choices:
375 125 100 150

Answer 1

First, we calculate the expected number of red balls in Bowl A:
Expected number of red balls in Bowl A = (75/100) * 500 = 375

Next, we calculate the expected number of white balls in Bowl A:
Expected number of white balls in Bowl A = (25/100) * 500 = 125

The estimated difference in the expected number of red and white balls in Bowl A is:
375 - 125 = 250

Therefore, the closest answer choice is 150.
