Answer 2

`\boxed{\boxed{C(7,4)=35}}`

Step-by-step explanation:

Here, we have to calculate

`C(7,4)=\dbinom{7}{4}`

From combination we know that,

`\dbinom{n}{r}=(n!)/(r!(n-r)!)`

Here,

n = 7 and r = 4, so putting these,

`\dbinom{7}{4}=(7!)/(4!(7-4)!)`

`=(7!)/(4!\ 3!)`

`=(5040)/(24* 6)`

`=(5040)/(144)`

`=35`
