Question 1181172
<br>
The solution from the other tutor shows one standard method for finding the probability for a problem like this.<br>
There is another basic method you should know, since it is more useful when the problems get more involved.<br>
You are choosing 5 cards from a deck of 52 cards; the number of ways you can do that is "52 choose 5" = C(52,5).<br>
The outcome you want is that all 5 cards are face cards.  There are 12 face cards in the deck, so the number of favorable outcomes is 12 choose 5 = C(12,5).<br>
The probability of drawing all face cards is then<br>
{{{C(52,5)/C(12,5)}}} which is about 0.00030474, or 0.03%.<br>
