Answer:
Number of ways of selecting two students is 15
Step-by-step explanation:
number of ways of selecting n out of r is given by
[tex]n_{C_{r} } =\frac{n!}{r!(n-r)!}[/tex]
It is given that there are 6 seniors on student council.
2 students are selected for district meeting
So we have [tex]n= 6[/tex] and [tex]r=2[/tex]
number of ways of selecting two students =[tex]6_{C_{2} } [/tex]
=[tex]\frac{6!}{2!(6-2)!}[/tex]
=[tex]\frac{6!}{2!4!}=15[/tex]
So we have number of ways of selecting two students is 15
