##### Practice A3
Lilyhui
This question was the same as the midterm the answer is (10 C 3)x(5C2)^3 divided by (50 C6) there are four generations of choices for the numerator. The first chooses the three distinct values from the 10 and the subsequent generations of choices chooses the pair of color for each value

Don't you get 1 less choice of value every time you pick one? So shouldn't it be (5C2)(10C1)(5C2)(9C1)(5C2)(8C1) divided by (50C6) ?

10C3 because you pick the three values simultaneously (no order in which you choose the cards). If you pick the cards that way you have to deorder the final answer

So, in this case, it's not the same as playing a hand of poker where cards are given out one by one?

Unless the question states I dont think it can be assumed. Since it was a midterm question, we're not required to have any knowledge of poker game rules so I would think that its not the same.
