Question

Use the table to answer the question. Bowl A: 5 white balls and 15 red balls. Bowl B: 16 white balls and 4 red balls. Bowls A and B contain a number of white balls and red balls. Simon repeatedly selected a ball from both bowls and recorded the results in a table. Using Simon's results, what's the experimental probability of picking a red ball from Bowl A? The answer needs to be in percent form.

Answer 1

From Simon's results, there are a total of 5 + 15 = 20 balls in Bowl A, and he picked a red ball 15 times.

So, the experimental probability of picking a red ball from Bowl A is 15/20 = 0.75.

Converting to percent form, the experimental probability of picking a red ball from Bowl A is 0.75 * 100% = 75%.
