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?

A- 100
B- 300
C- 50
D- 200

Answer 1

Bowl B has a total of 500 balls, so the expected number of white balls in Bowl B is:

(60/100) x 500 = 300

And the expected number of red balls in Bowl B is:

(40/100) x 500 = 200

The estimated difference between these two numbers is:

300 - 200 = 100

Therefore, the answer is A- 100.

Answer 2

u sure

Answer 3

Yes, I'm sure. The answer is A- 100.

Answer 4

And how do you know

Answer 5

I calculated the expected number of white and red balls in Bowl B based on the given information in the table.

For Bowl B:
- The total number of balls is 500.
- The proportion of white balls is 60/100 or 0.6.
- The proportion of red balls is 40/100 or 0.4.

So, the expected number of white balls in Bowl B is:

0.6 x 500 = 300

And the expected number of red balls in Bowl B is:

0.4 x 500 = 200

The estimated difference in the expected number of white and red balls in Bowl B is:

300 - 200 = 100

Therefore, the answer is A- 100.
