Both ANB container number of white and red balls. Simon repeatedly selected a ball from both bowls and recorded the results in the table. He picked 15 red balls and five white balls using the results. What is the experimental probability of picking a red ball from bowl an answer needs to be written in percent

In order to calculate the experimental probability of picking a red ball from bowl A, we can use the information provided:

- Simon picked 15 red balls from both bowls combined.
- According to the table, bowl A contains 12 white balls and 8 red balls.
- Therefore, Simon must have picked 7 red balls from bowl A (since 15 - 8 = 7 red balls were picked from bowl A).

To calculate the experimental probability of picking a red ball from bowl A, we use the formula:

Experimental Probability = Number of Favorable Outcomes / Total Number of Outcomes

In this case, the number of favorable outcomes is the number of red balls picked from bowl A, which is 7. The total number of outcomes is the total number of balls picked from both bowls, which is 20 (15 red balls + 5 white balls).

Experimental Probability = 7 / 20 ≈ 0.35

To express this as a percentage, we multiply by 100:

Experimental Probability ≈ 0.35 x 100% = 35%

Therefore, the experimental probability of picking a red ball from bowl A is 35%.
