Question

A student entering a doctoral program in educational psychology is required to select 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 like-hood that EPR 615, EPR 650 and EPR 636 will be selected.

Answer 1

A) The possible three-course selections are as shown below.

B) The likelihood of selecting the combinations is 0.1 since there are 10 combinations in total.

How to solve probability combinations?

A combination operator can be used when we need to find the number of ways to select "k" items from a set of "n" items. It is also called a 'choose' operator where it is read as 'n choose k' and is represented and calculated as given below

From the choices given, there are 5 courses which are given below:

EPR 605

EPR 643

EPR 648

EPR 674

EPR 681

We need to find the combinations of 3 of these given 5 courses, which are given below (omitting the course code, EPR):

605-643-648

605-643-674

605-643-681

605-648-674

605-648-681

605-674-681

643-648-674

643-648-681

643-674-681

648-674-681

10 of the given choices of combinations are possible since they do not include a repeated course number.

The likelihood of selecting the combination of EPR 681, EPR 648, and EPR 605 is 0.1 since there are 10 combinations in total.

Complete question is;

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.
