To calculate the experimental probability of picking a red ball from Bowl A, you need to find the ratio of the number of red balls selected from Bowl A to the total number of balls selected from Bowl A.
From the table:
- Number of red balls selected from Bowl A: 15
- Number of white balls selected from Bowl A: 5
First, calculate the total number of balls selected from Bowl A: \[ \text{Total balls from Bowl A} = \text{Number of white balls} + \text{Number of red balls} = 5 + 15 = 20 \]
Now, calculate the probability of picking a red ball from Bowl A: \[ \text{Probability of red ball from Bowl A} = \frac{\text{Number of red balls}}{\text{Total balls from Bowl A}} = \frac{15}{20} \]
Now, simplify the fraction: \[ \frac{15}{20} = \frac{3}{4} = 0.75 \]
To convert this probability into a percentage, multiply by 100: \[ 0.75 \times 100 = 75% \]
Therefore, the experimental probability of picking a red ball from Bowl A is 75%.
