Answer 1

Given

Course List: EPR 676 , EPR 614 , EPR 616 , EPR 640 , EPR 654 = 5 courses

a)

There are 5 courses. 5C2 = 10 combinations.

All possible courses:

(676, 614), (676,616), (676, 640), (676, 654)

(614,616), (614, 640), (614, 654)

(616, 640), (616, 654)

(640, 654)

​(b)

Comment on the likelihood that

EPR 616 and EPR 654 will be selected.          

Probability of EPR 602 and EPR 684 will be selected = 1/10

= 0.10

There are 0.10 probability that EPR 616 and EPR 654 will be selected.
