A tutorial lab is open at a certain university from 9 AM to 3 PM.
Between the hours of 11 AM and 1 PM, there are, on average, 10 students in the tutorial lab.
The probability that any student at this university will visit the lab between 11 AM and 1 PM is 0.2.
The probability that any student in the lab is being tutored in Anatomy and Physiology (A&P) is 0.35.
Use this information to answer the following questions. Assume the probability of the subject being tutored to each student is independent. Also assume the probability of each student entering the tutorial lab is independent.
(a) If we wish to determine the probabililty that at least 7 students will be in the tutorial lab between 11 AM and 1 PM, which distribution should be used?A. BinomialB. PoissonC. GeometricD. None of these(b) If we wish to determine the probability that the third student entering the tutorial lab between 11 AM and 1 PM is the first student to request A&P tutoring, which distribution should be used?A. PoissonB. GeometricC. BinomialD. None of these
