Q: The probability that person A completes all the tasks assigned is 50% and that of person B is 20%. F

Let A be the event that all tasks are completed and Ei is the event that a person is selected. Then, P(A) = P(E1) P(A|E1) + P(E2) P(A|E2) =(12)(50100)+(12)(20100) = 0.35

A 0.15

B 0.25

C 0.11

D 0.35

E 0.45

Suppose there is a pond with fishes and “n” number of fishermen living around it. Let a i is time spent fishing per day by player i. Thus total time per day is a 1 + ... + a n. The number of fish available at any time is given by: (2000- Σ i a i ). The number of fish caught by a fisherman “j” is: a j (2000- Σ i a i ). Then what would be the best response of fisherman “i” to maximise his total?
