Use the table to answer the question.
Number of White Balls Selected Number of Red Balls Selected
Bowl A 5 15
Bowl B 16 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. Using Simon’s results, what is the experimental probability of picking a red ball from Bowl A? The answer needs to be in percent form.

To find the experimental probability of picking a red ball from Bowl A, we need to calculate the total number of times a red ball was selected from Bowl A and divide it by the total number of selections from Bowl A.
In Bowl A, 15 red balls were selected.
Simon repeated the selection process for both bowls a total of 20 times (15 times from Bowl A and 5 times from Bowl B).
Therefore, the experimental probability of picking a red ball from Bowl A is 15/20 = 0.75 or 75%.
Therefore, the answer in percent form is 75%.
Correct answer: 75%
