Question

A student entering a doctoral program in educational psychology is required to select three courses from the list of courses provided as part of his or her program.

(a) List all possible three-course selections. 

(b) Comment on the likelihood that EPR 662, EPR 609, and EPR 656 will be selected.

Answer 1

(A)

option B is incorrect because 671 is not a coure

option F is incorrect because only two courses selected

option G is incorrect because 608 is selected twice

Optin K is incorrect because 662 is selected twice

Except these options, all are correct answer

Option A, C, D, E,H,I,J,L,M and N are correct

(b) there are 5 courses in total and we can select only 3 at a time

So, total number of possible selection = $\binom{5}{3} = 5!/[(5-3)!*3!] = 10$

So, there are 10 possible ways to select three courses at a time

So, the likelihood of selecting EPR 662, EPR 609 and EPR 656 = 1/10 = 0.1
