Suppose that there is a 1 in 40 chance of injury on a single skydiving attempt. A friend claims there is a 100% chance of injury if a skydiver jumps 40 times. Assume that the results of repeated jumps are mutually independent.What is the maximum number of jumps, n, the skydiver can make if the probability is at least 0.70 that all n jumps will be completed without injury? (Round your answer down to the nearest integer.)
