Using the image above, what is the theoretical probability of picking a yellow counter in simplest form?

30%
50%
70%
100%
Joan picks a random counter out of the bag 10 times, and she got a yellow counter 7 times. What is the experimental probability of picking a yellow?
305
50%
70%
100%

Answer 1

To find the theoretical probability of picking a yellow counter, you need the total number of counters and the number of yellow counters. If the image showing these counts is not available, we cannot calculate that directly. However, if we assume that you have the necessary information:

1. **Theoretical Probability**: This is calculated as the number of favorable outcomes (yellow counters) divided by the total number of outcomes (total counters). If the theoretical probability is given as 30%, 50%, 70%, or 100%, you would choose the correct option depending on the counts provided.

2. **Experimental Probability**: This is calculated based on Joan's experiment. She picked a yellow counter 7 times out of 10 attempts. The experimental probability is therefore \( \frac{7}{10} \) or 70%.

So the answers would be:
- Theoretical probability: (choose the relevant percentage based on given data)
- Experimental probability: 70%
