The correct Answer is:
To solve the problem, we need to find the probability of the intersection of two independent events A and B, denoted as P(A ∩ B). ### Step-by-Step Solution: 1. **Identify the given probabilities**: - P(A) = 2/5 - P(B) = 1/3 2. **Understand the concept of independent events**: - Two events A and B are independent if the occurrence of one does not affect the occurrence of the other. This means that the probability of both A and B occurring together is the product of their individual probabilities. 3. **Use the formula for independent events**: - For independent events, the probability of the intersection is given by: \[ P(A \cap B) = P(A) \times P(B) \] 4. **Substitute the values into the formula**: - Substitute P(A) and P(B) into the formula: \[ P(A \cap B) = \left(\frac{2}{5}\right) \times \left(\frac{1}{3}\right) \] 5. **Perform the multiplication**: - Multiply the fractions: \[ P(A \cap B) = \frac{2 \times 1}{5 \times 3} = \frac{2}{15} \] 6. **Conclusion**: - Therefore, the probability of the intersection of A and B is: \[ P(A \cap B) = \frac{2}{15} \] ### Final Answer: \[ P(A \cap B) = \frac{2}{15} \] ---
