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 find the experimental probability of picking a red ball from Bowl A, we need to calculate the total number of balls in Bowl A and then find the ratio of red balls selected to the total number of balls selected.

From the table:

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

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

Now, the probability of picking a red ball from Bowl A is given by:

\[ \text{Probability of red ball from Bowl A} = \frac{\text{Number of red balls selected from Bowl A}}{\text{Total number of balls selected from Bowl A}} = \frac{15}{20} \]

Now, simplify the fraction:

\[ \frac{15}{20} = 0.75 \]

To convert this probability into percent form, we multiply by 100:

\[ 0.75 \times 100 = 75% \]

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