Question

This table shows the number of white and red balls Simon selected from Bowl A and Bowl B.
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.

Answer 1

To calculate the experimental probability of picking a red ball from Bowl A, we need to determine the total number of balls selected from Bowl A and the number of red balls selected from it.

From the table:

• Number of red balls selected from Bowl A = 15
• Number of white balls selected from Bowl A = 5

Total balls selected from Bowl A = Number of red balls + Number of white balls
= 15 + 5
= 20

The experimental probability \( P \) of picking a red ball from Bowl A is calculated as follows:

\[ P(\text{Red from Bowl A}) = \frac{\text{Number of Red Balls from Bowl A}}{\text{Total Balls from Bowl A}} = \frac{15}{20} = 0.75 \]

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

\[ P(\text{Red from Bowl A}) = 0.75 \times 100 = 75% \]

Thus, the experimental probability of picking a red ball from Bowl A is 75%.
