Answer:
4512.
Step-by-step explanation:
We are asked to find the number of five-card hands (drawn from a standard deck) that contain exactly three fives.
The number of ways, in which 3 fives can be picked out of 4 available fives would be 4C3. The number of ways in which 2 non-five cards can be picked out of the 48 available non-five cards would be 48C2.

We can choose exactly three fives from five-card hands in
ways.

Therefore, 4512 five card hands contain exactly three fives.
You need to do 175 divided by 3.
