A sales manager is considering 3 salespersons (A, B, and C) that could potentially hit their target soon. The probability that salesperson A will hit their target is 0.8 while that of B and Care 0.7 and 0.7 respectively. Assume these events are independent. Hint: Draw a probability tree/tree diagram. Do not round calculation results. What is the probability that 1. all 3 salespersons will hit their target? 0.392 2. none of the 3 salespersons will hit their target? 0.018 3. not all 3 salespersons will hit their target? 0.608 4. only salesperson B will hit their target? 0.042 5. only salespersons C and A will hit their target? 0.112 x х 6. only salesperson A will not hit their target? 0.112 х

7. at least one salesperson will hit their target? 8. no more than two salespersons will hit their target? 9. only one salesperson will hit their target? 10. salesperson C will not hit their target given both B and A hit their target?
