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?
First, we need to find the total number of balls in Bowl A. Since Bowl A contains 45 white balls and 55 red balls, the total number of balls in Bowl A is 45 + 55 = 100.
Next, we can find the ratio of white balls to total balls in Bowl A by dividing the number of white balls by the total number of balls: 45 / 100 = 0.45.
We can then use this ratio to estimate the number of white balls in Bowl B. Since Bowl B contains 500 balls, we estimate that Bowl B contains 0.45 * 500 = 225 white balls.
Similarly, we can estimate the number of red balls in Bowl B by subtracting the estimated number of white balls from the total number of balls in Bowl B: 500 - 225 = 275 red balls in Bowl B.
Finally, we can find the estimated difference in the expected number of white and red balls in Bowl B by subtracting the estimated number of red balls from the estimated number of white balls: 225 - 275 = -50.
Therefore, the estimated difference in the expected number of white and red balls in Bowl B is -50.
