Answers
1/10 is the probability if 5 Subjects in total , 1/20 if 6 subjects in total
Step-by-step explanation:
One important thing is missing here
Subjects
assume there are 5 Subjects
EPR 639
EPR 651
EPR 666
EPR 671
EPR 685
EPR 639 , EPR 651 , EPR 666 , EPR 671 , EPR 685
3 Subjects out of 5 subjects can be selected in ⁵C₃ = 10 Ways
all possible three-course selections.
EPR 639 , EPR 651 , EPR 666
EPR 639 , EPR 651 , EPR 671
EPR 639 , EPR 651 , EPR 685
EPR 639 , EPR 666 , EPR 671
EPR 639 , EPR 666 , EPR 685
EPR 639 , EPR 671 , EPR 685
EPR 651 , EPR 666 , EPR 671
EPR 651 , EPR 666 , EPR 685
EPR 651 , EPR 671 , EPR 685
EPR 666 , EPR 671 , EPR 685
likelihood that EPR 671 , EPR 685 , EPR 639 will be selected.
= 1/10
if total 6 subject
3 Subjects out of 6 subjects can be selected in ⁶C₃ = 20 Ways
likelihood that EPR 671 , EPR 685 , EPR 639 will be selected.
= 1/20
