There are three tasks; A, B and C. Tasks A and B are independent each other. If both A and B finishes, then task C can start. The chance of delay for task A is 30 % and the chance of delay for task B is 50 %. What is the probability that the task C starts on time? a. 94% b. 56% c. 35% d. 14%

Step 1
Since they are independent, we can multiply their probabilities of finishing on time. The probability of task A finishing on time is 1 - 0.30 = 0.70, and the probability of task B finishing on time is 1 - 0.50 = 0.50. Show more…
