Sadly all the answers I got were wrong... Can someone help? THANKS!
+1008 You said you've been working on it, in a few hours you should make a bit of progress, can you share what you have done so far?
I tried to calculate the number of possibilities of Aces, 2s and 3 in the same hand as (4^3\times3^3\times2^3\times1^3)=13824, and the number of possibilities as \dbinom{12}{3}\dbinom{8}{3}\dbinom{4}{3}=49280. 13824/49280=\boxed{\frac{108}{385}}
Sorry, the latex doesn't work here...
+738 good job! you're on the right track! the numerator is correct, but the denominator isn't.
you got the 12 choose 3 part right, but not the rest.
think about it, if you've already chosen 3 cards, then there would be 12-3=9 cards left to choose from, not 8.
you're really close! you got this!
