792

Step-by-step explanation:

We know that the formula for the number of combinations of n things taken r at a time is given by :-

$C(n;r)=\dfrac{n!}{r!(n-r)!}$

Now, the number of combinations of 12 things taken 5 at a time is given by :-

$C(12;5)=\dfrac{12!}{5!(12-5)!}\\\\\\=\dfrac{12\times11\times10\times9\times8\times7!}{120\times7!}=\dfrac{11\times9\times8}{1}=792$

Hence, the number of different ways can you show 5 of the 12 movies on the big screen = 792
