Final Answer :
B
Explanation :
The reliability of the entire job is the probability that all three tasks are performed correctly. Assuming the tasks are independent, we can multiply the probabilities of each task:
0.98 x 0.99 x 0.97 = 0.9411, or 94.11%. Therefore, the best choice is B.
0.98 x 0.99 x 0.97 = 0.9411, or 94.11%. Therefore, the best choice is B.
