Answer:

66

Step-by-step explanation:

11 + 4 = 15

Answer: 4

Step-by-step explanation: Since the probability of man hitting the target is 14 so for four consecutive shots it will be (14)4=1256 which is wrong.

Now the book takes a different approach and finds the probability that he will not hit the target in one shot = 1−14=34 therefor the probability he will not hit the target in 4 shots is (34)4 and thus , the probability that he will hit the target at least in one of the four shots is 1- (34)4

Although I understand the books approach - I wanted to know why my approach is wrong ? doesnt it also calculate the probability of hitting the target in 4 shots
