Answer:
There are 685464 ways of selecting the 5-card hand
Step-by-step explanation:
Since the hand has 5 cards and there should be at least 1 card for each suit, then there should be 3 suits that appear once in the hand, and one suit that apperas twice. 
In order to create a possible hand, first we select the suit that will appear twice. There are 4 possibilities for this. For that suit, we select the 2 cards that appear with the respective suit. Since there are 13 cards for each suit, then we have  possibilities. Then we pick one card of all remaining 3 suits. We have 13 ways to pick a card in each case.
 possibilities. Then we pick one card of all remaining 3 suits. We have 13 ways to pick a card in each case. 
This gives us a total of 4*78*13³ = 685464 possibilities to select the hand.
