The expected number of white balls in Bowl B can be estimated using the percentage of white balls selected from it. Since 60 white balls were selected out of 100 balls in total (60 white + 40 red) from Bowl B, the estimated percentage of white balls in Bowl B is 60%.
If there are 500 balls in Bowl B, the estimated number of white balls would be 60% of 500, which is 300 white balls.
Similarly, the estimated number of red balls in Bowl B can be calculated as 40% of 500, which is 200 red balls.
Therefore, the estimated difference in the expected number of white and red balls in Bowl B is 300 (white) - 200 (red) = 100.
So, the answer is 100.
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?

To further elaborate, in Bowl B, Clark selected 60 white balls out of 100 total balls selected. This means that 60% of the balls in Bowl B are white. Since it is given that Bowl B contains 500 balls in total, we can estimate that there are 60% of 500 white balls, which equals 300 white balls in Bowl B.
Similarly, using the same logic, we can estimate that there are 40% of 500 red balls in Bowl B, which equals 200 red balls in Bowl B.
Therefore, the estimated difference in the expected number of white and red balls in Bowl B is calculated by subtracting the number of red balls from the number of white balls: 300 white balls - 200 red balls = 100.
Hence, the estimated difference in the expected number of white and red balls in Bowl B is 100.

Therefore, the estimated difference in the expected number of white and red balls in Bowl B is calculated by subtracting the number of red balls from the number of white balls: 300 white balls - 200 red balls = 100.
Hence, the estimated difference in the expected number of white and red balls in Bowl B is 100.
can you make it more scietific
Certainly.
To estimate the difference in the expected number of white and red balls in Bowl B scientifically, we can use the concept of proportions. In this case, we know that 60% of the balls in Bowl B are white, which equates to 300 white balls out of 500 total balls in Bowl B. Similarly, 40% of the balls in Bowl B are red, which equates to 200 red balls out of 500 total balls in Bowl B.
When calculating the difference in the expected number of white and red balls, we can utilize the following formula:
Difference = Expected White Balls - Expected Red Balls
Expected White Balls = (Percentage of White Balls in Bowl B) x (Total Number of Balls in Bowl B)
Expected White Balls = 0.6 * 500 = 300 white balls
Expected Red Balls = (Percentage of Red Balls in Bowl B) x (Total Number of Balls in Bowl B)
Expected Red Balls = 0.4 * 500 = 200 red balls
Therefore, the estimated difference in the expected number of white and red balls in Bowl B is:
Difference = 300 white balls - 200 red balls
Difference = 100 balls
Hence, scientifically, the estimated difference in the expected number of white and red balls in Bowl B is 100 balls.

Therefore, the estimated difference in the expected number of white and red balls in Bowl B is:
Difference = 300 white balls - 200 red balls
Difference = 100 balls
Hence, scientifically, the estimated difference in the expected number of white and red balls in Bowl B is 100 balls.
