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?
Bowl A= Amount of White Balls are 25 and amount of red balls are 75
Bowl B= Amount of white balls are 40 and amount of red balls are 60
To find the estimated difference in the expected number of red and white balls in Bowl A, we first need to find the expected number of white and red balls in Bowl A based on the proportion of white and red balls in each bowl.
In Bowl A, the proportion of white balls is 25/100 = 0.25 and the proportion of red balls is 75/100 = 0.75
In Bowl B, the proportion of white balls is 40/100 = 0.4 and the proportion of red balls is 60/100 = 0.6
Now, let's calculate the expected number of white and red balls in Bowl A:
Expected number of white balls in Bowl A = 0.25 * 500 = 125
Expected number of red balls in Bowl A = 0.75 * 500 = 375
The expected difference in the number of red and white balls in Bowl A is:
Expected difference = Expected number of red balls - Expected number of white balls
Expected difference = 375 - 125
Expected difference = 250
Therefore, the estimated difference in the expected number of red and white balls in Bowl A is 250.
