$\boxed{ \tt^{n} C_{r} = \frac{n!}{r!(n - r)!} }$

<h3>Calculation, </h3>

Plug in the values:

Required number of ways = ²C7

n = 7
r = 5

$\sf \frac{7!}{5!(7 - 5)!}$

$\sf \frac{7 \times 6 \times \cancel{5!}}{ \cancel{5! }\times 2!}$

$\sf \frac{7 \times 6 }{ 2!}$

$\sf \frac{42 }{ 2!}$

$\sf \frac{42 }{ 2} = 21$
