Answer 1

Solution:-

Total number of courses = 5

Different courses = EPR635, EPR658, EPR645, EPR622, EPR620

Number of three courses possible = ⁵C₂ = 10

a) All possible three courses are

EPR635, EPR658, EPR645

EPR635, EPR645, EPR622

EPR635, EPR622, EPR620

EPR635, EPR658, EPR622

EPR635, EPR658, EPR620

EPR635, EPR645, EPR620

EPR658, EPR645, EPR622

EPR658, EPR645, EPR620

EPR658, EPR622, EPR620

EPR645, EPR622, EPR620

b) The likelihood of EPR635, EPR658, EPR622 = 0.10.

The number of courses having EPR635, EPR658, EPR622 = 1

Total courses = 10

The likelihood of EPR635, EPR658, EPR622 = 1/10

The likelihood of EPR635, EPR658, EPR622 = 0.10
