A certain disease has a prevalence of in a population. The rate of false 4 positives is 10% and and the rate of false negatives is 5%. If you are exposed to the disease, then probability that you contract it is . You can only contract the disease by sharing food. Suppose that you meet 10 people, that each person tests negative for the disease, and that you share food with each of them exactly three times. What is the probability that you contract the disease?
a quiz for a psychology class consists of ten questions, the questions are multiple choices with five possible answers each with only one correcct answer. if the student did not study and is guessing for all ten questions (x is the number of correct answers a students get correct) A- what is the probability of that student gettting one correct answer? B- what is the probability of that student getting a passing grade (70% or more correct is passing)
