From the table, we can see that Bowl B contains 60 white balls and 40 red balls. Since there are 500 balls in Bowl B, we can estimate the total number of white balls in Bowl B by setting up a ratio:
60 white balls / x total balls = 500 balls / 1 total bowl
Cross-multiplying, we get:
60x = 500
x = 500 / 60
x = 8.33 (rounded to 8)
This means that there are approximately 8 groups of 60 white balls in Bowl B, which equals 480 white balls.
Similarly, the estimated number of red balls in Bowl B would be 500 - 480 = 20 red balls.
Thus, the estimated difference in the expected number of white and red balls in Bowl B would be: 480 - 20 = 460 white balls.
The closest answer choice is 300.
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?
