This table shows the number of white and red balls selected from Bowl A and Bowl B.
Number of White Balls Selected Number of Red Balls Selected
Bowl A 5 15
Bowl B 16 4
Bowls A and B contain a number of white and red balls. Simon repeatedly selected a ball from both bowls and recorded the results in a table. If there are 36 balls in Bowl A, estimate the number of white balls based on Simon’s results.

To estimate the number of white balls in Bowl A based on Simon's results, we can use the proportion of the balls selected.

From the table, we have:

  • Bowl A: 5 white balls and 15 red balls
  • Bowl B: 16 white balls and 4 red balls

First, we calculate the total number of balls selected in Bowl A:

  • Total from Bowl A = 5 (white) + 15 (red) = 20

Next, we find the proportion of white balls selected from Bowl A:

  • Proportion of white balls in Bowl A = 5 / 20 = 1/4

If Bowl A has a total of 36 balls, we can estimate the number of white balls in Bowl A using this proportion:

  • Estimated number of white balls = Total balls in Bowl A * Proportion of white balls
  • Estimated number of white balls = 36 * (1/4) = 9

Therefore, the estimated number of white balls in Bowl A is 9.
