To estimate the number of white balls in Bowl A, we need to first calculate the total number of white and red balls based on Simon's results.
From the table, Simon has selected a total of 20 balls (5 white + 15 red) from Bowl A and 20 balls (16 white + 4 red) from Bowl B.
Therefore, the total number of white balls selected is 5 + 16 = 21 and the total number of red balls selected is 15 + 4 = 19.
Since Simon selected a total of 40 balls (20 from each bowl), and there are a total of 36 balls in Bowl A, the estimated number of white balls in Bowl A can be calculated as:
Estimated number of white balls in Bowl A = (21/40) * 36 = 18
Therefore, the correct answer is 18.
Use the table to answer the question.
bowl A: white: 5 red :15
bowl B: white 16 red: 4
Bowls A and B contain a number of white and red balls. Simon repeatedly selected a ball from both bowls and recorded the results in a table. If there are 36 balls in Bowl A, estimate the number of white balls based on Simon’s results.
