Answer: 2405970 ways

Step-by-step explanation:

When the order of selecting r individuals out of n individual , we use permutations.

The number of permutations of r things taking out of n things is given by :-

^nP_r=\dfrac{n!}{(n-r)!}

Given : There are 135 people and three door prizes .

i.e. n= 135 , r= 3

Then, the total number of ways = ^{135}P_3=\dfrac{135!}{(135-3)!}

=\dfrac{135\times134\times133\times132!}{132!}\\\\=135\times134\times133\\\\=2405970

Hence, there are 2405970 ways to distribute door prizes of $7,500, $750 and $75 .
