(Round to five decimal places as needed) (b) What is the probability of selecting a jury of all faculty? (Round to five decimal places as needed) (c) What is the probability of selecting a jury of four students and three faculty? (Round to five decimal places as needed) Enter your answer in each of the answer boxesExplanation / Answer
Number of ways in which r items can be selected from n = nCr = n!/(r! x (n-r)!)
a) P(jury of all students) = 7C7/14C7
= 0.00029
b) P(jury of all faculty) = 7C7/14C7
= 0.00029
b) P(jury of 4 students and 3 faculty) = 7C4 x 7C3 / 14C7
= 35x35/3432
= 0.35693
