A committee of 4 can be formed __ ways

In how

In a committee the order doesn't matter, in other words if we choose members of a committee ABC, this is the same as a committee of members BCA. A committee of 4 chosen from 7 students is then,

$C(7,4) = \frac{7!}{(7-4)!4!} = \frac{7!}{3!4!} = 35$

Surround your text in `*italics*`

or `**bold**`

, to write a math equation use, for example, `$x^2+2x+1=0$`

or `$$\beta^2-1=0$$`
