Using the Combination Formula

[tex]{ \tt{C(n,r)= \frac{n!}{r!(n - r)!} }}[/tex]

[tex]{ \tt{ C(3,1)= \frac{3!}{1!( 3- 1)!} }}[/tex]

[tex]{ \tt{C = \frac{3 \times 2 \times \cancel{ 1!}}{ \cancel{1!} \: 2!} }}[/tex]

[tex]{ \tt{C = 3 \times 2}}[/tex]

[tex]{ \large{ \color{pink}{ \boxed{ \tt{C = 6}}}}}[/tex]
