Question

Use the table to answer the 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. (1 point) Responses 25% 25% 78.95% 78.95% 75% 75% 37.5%

Answer 1

To find the experimental probability of picking a red ball from Bowl A, we need to use the results from the selections made by Simon.

From the table:

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

The 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 the formula:

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

Substituting in the values:

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

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

\[ 0.75 \times 100 = 75% \]

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