You can put this solution on YOUR website! If you draw 5 cards from a standard 52 card deck, what is the probability of getting 5 numbered cards?
-----
Assuming the numbered cards are 2 thru 10 you have 36 numbered cards
----
P(5 numbered cards) = 36C5/52C5
=(36*35*34*33*32)/(52*54*53*52*51)
= 0.1451
==========
