b. Two people ? and ? are independently shoot at the same target once, and the hit rate is 0.6 and 0.5, respectively. Given that the target is hit, what is the probability that it is hit by person ??
Homework Answers
P(A) = 0.6
P(B) = 0.5
P(target is hit) = P(A) + P(B) - P(A) * P(B)
= 0.6 + 0.5 - 0.6*0.5
= 0.8
P(A|target is hit) = P(A)/P(target is hit) = 0.6/0.8 = 0.75
Required probability = 0.75

Two marksmen shoot at a target simultaneously. Shooter A is known to have a 70% chance of hitting the target on any attempt. Person B has 40% accuracy. After the target is hit for the first time, it is revealed that A shot 5 shots while B shot 12. What is the probability that it was A who hit the target? What is the probability that person B hit the target? (Assume that accuracies of the shots remain the same...

An archer is given five arrows and is told to shoot at a target until he has hit the target or has used up the five arrows. The probability of a hit on each shot is 0.8, independently of the other shots. Let the number of arrows used by the archer be represented by the random variable X. a) (6 points) Find the probability mass function of X. b) (6 points) What is the probability that the archer has to...

4. Three hunters shoot first hu at the same deer simultaneously. They hit or miss independently of each other nter hits with probability 1/3, the second one with probability 1/4, and the third one with bability 1/5. Calculate the probability that the deer will be hit at least once.

Four people working independently on an assembly line all perform the same task. The time (in minutes) to complete this task for person i, for i=1,2,3,4, has a uniform distribution on the interval [0, i]. Suppose each person begins the task at the same time. a) What is the probability that person 2 takes less than 90 seconds to complete the task? b) What is the average completion time for each person? c) What is the probability that all four...

10. Three candidates participated in a shooting game. There are required to shoot a target and each of them is given only a chance. Let K; represent the event that candidate number i shot the target, i=1, 2,3. If every shot is independent with probabililties P(K1)=0.5, P(K2)=0.8 and P(K3)=0.9, evaluate the probability that (i) exactly a participant shot the target? (ii) none of them shoot the target? (iii) at least there is a shot at the target?

The probability that Jane hits the target on any given attempt is 0.86. The probability that Edna hits the target on any given attempt is 0.64. If the two students behave independently, find the probability that if both women shoot at the target at least one of them hits the target? Give your answer to 3 places of decimal. Your Answer:

Barbara and Diane go target shooting. Suppose that each of Barbara’s shots hits a wooden duck target with probability p 1 , while each shot of Diane’s hits it with probability p 2 . Suppose that they shoot simultaneously at the same target. If we learn that the wooden duck is knocked over (indicating a hit), what is the probability that (a) both shots hit the duck? (b) Barbara’s shot hit the duck? What independence assumptions have you made?

Two people C and D are shooting at a target one after the other, until one of them hits the target. The probability of C and D hitting the target are respectively given by pC and pD. Assume that the success or failure of hitting the target is statistically independent for each shot. Evaluate the probability that C hits the target before D if C starts shooting first.

Two fighter jets are in a dogfight. Jet "A" is about to shoot "Jet B", which is right in front of him. Jet "B", knowing that he is in trouble, decides to shoot first. He aims his gun directly behind him and fires. The bullets hit their target, Jet "A". However unknown to the pilots, they are passing by the top of a tall mountain and a climber standing on the top of the mountain also gets hit by the...
