A research study uses 800 men under the age of 55. Suppose that 30% carry a marker on the male chromosome that indicates an increased risk for high blood pressure. If 5 men are selected randomly and tested for the marker, what is the probability more than 1 man doesn't have the marker? Include in the solution the values of K, n, and N. 0.9696

Transcribed Image Text:Consider the time to recharge the flash in cell-phone cameras. Assume that the probability that a
camera passes the test is 0.85 and the cameras perform independently. Determine the following.
Probability that the third camera that passed occurs on the third camera tested. Expected number
of cameras tested to obtain 3 passed cameras. Let X be a negative binomial random variable.
