3.5 The probability in the simplest form that a leamer from the class is younger than 20 years.

To determine the probability that a learner from the class is younger than 20 years, we need specific information about the ages of the learners in the class. Here's what would typically be required to solve this problem: 1. **Total Number of Learners in the Class:** This gives the sample space for the probability calculation. 2. **Number of Learners Younger Than 20:** This is the favorable outcome. 3. **Age Distribution (if applicable):** If ages are continuous or follow a certain distribution, information about that distribution is necessary. **General Formula:** The probability \( P \) that a randomly selected learner is younger than 20 years can be calculated using the formula: \[ P(\text{Younger than } 20) = \frac{\text{Number of learners younger than } 20}{\text{Total number of learners in the class}} \] **Example:** Suppose there are 30 learners in the class, and 8 of them are younger than 20 years. \[ P(\text{Younger than } 20) = \frac{8}{30} = \frac{4}{15} \] So, the probability in its simplest form is \( \frac{4}{15} \). **Next Steps:** Please provide the following details to determine the exact probability: - The total number of learners in the class. - The number of learners who are younger than 20 years. With this information, I can help you calculate the probability accurately.
