Q1. The presence of bacteria in a urine sample (bacteriuria) is sometimes associated with symptoms of kidney disease in women. Suppose a determination of bacteriuria has been made over a large population of women at one point in time and 5% of those sampled are positive for bacteriuria. b. If a sample size of 5 is selected from this population, what is the probability that I or more women are positive for bacteriuria? Suppose 200 women from this population are sampled. What is the probability that 3 or more of them are positive for bacteriuria?​
