If Bowl A has 45 white balls and bowl B has 60 white balls and bowl A has 55 red balls and bowl B had 40 red balls. If there are 500 balls in Bowl B, what is the estimates difference in the expected number of white balls and red balls in Bowl B

Answer 1

First, let's calculate the expected number of white balls in Bowl B:

There are 500 balls in Bowl B, with 60 white balls. So the probability of selecting a white ball from Bowl B is 60/500 = 0.12.

Therefore, the expected number of white balls in Bowl B is 500 * 0.12 = 60.

Now, let's calculate the expected number of red balls in Bowl B:

There are 500 balls in Bowl B, with 40 red balls. So the probability of selecting a red ball from Bowl B is 40/500 = 0.08.

Therefore, the expected number of red balls in Bowl B is 500 * 0.08 = 40.

The estimated difference in the expected number of white balls and red balls in Bowl B is 60 - 40 = 20 balls.
