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?

To find the estimated difference in the expected number of red and white balls in Bowl A, we need to know the proportion of red and white balls in both Bowl A and Bowl B.

Since the information provided only states that Bowl A contains a total of 500 balls, we do not have enough information to calculate the estimated difference in the expected number of red and white balls.

If more information on the proportion of red and white balls in Bowl A and Bowl B is provided, we can calculate the estimated difference.
