Suppose that there is a 1 in 60 chance of injury on a single skydiving attempt. A friend claims there is a 100% chance of injury if a skydiver jumps 60 times. Assume that the results of repeated jumps are mutually independent. (a) What is the probability that 60 jumps will be completed without an injury

Since the results are mutually exclusive then we compute the probability as:

Pr(1) =1/60 or = 0.167

Step-by-step explanation:

Pr(1) is given as the probability of one injury after 60 trails.

Probability is given by : the required outcome/the total number of possible outcome

0.84 dang lotta people are looking for this lol or if you round up its 1 but the overall answer to that is 0.84

step-by-step explanation:

4/6 = 2/3

so it should take 3/3 hours per man. so 9 hours is the answer 3*3 =9

step-by-step explanation:
