In Bowl A, the ratio of red to white marbles selected is 75:25, which simplifies to 3:1. This means that for every 4 balls selected from Bowl A, 3 of them are red and 1 of them is white.
If we apply this ratio to all 500 balls in Bowl A, we can estimate that 375 of them are red and 125 are white.
In Bowl B, the ratio of red to white marbles selected is 60:40, which simplifies to 3:2. This means that for every 5 balls selected from Bowl B, 3 of them are red and 2 of them are white.
This information helps us estimate the expected number of red and white balls in Bowl A.
Expected number of red balls in Bowl A: 375
Expected number of white balls in Bowl A: 125
Estimated difference in the expected number of red and white balls in Bowl A: 375 - 125 = 250
Therefore, the estimated difference in the expected number of red and white balls in Bowl A is 250.
Bowls A and B contain a number of white and red balls. Raya repeatedly selected a ball from both bowls and recorded the results in a table. If there are 500 balls in Bowl A, what is the estimated difference in the expected number of red and white balls in Bowl A?
