Please help, I'm really stuck.
The deck for a card game contains 30 cards. 10 are red, 10 yellow, 5 blue, and 1 green, and 4 are wild cards. Each player is randomly dealt a five-card hand.
a) What is the probability that a hand will contain exactly two wild cards?
b) What is the probability that a hand will contain two wild cards, two red cards, and one blue cards?

a) What is the probability that a hand will contain exactly two wild cards?
\(\text{Prob of exactly 2 wild cards}\\ =\frac{\text{number with exactly 2 wild cards}}{\text{number of possible hands}}\\ =\frac{4C2 * 26C3}{30C5}\\ =\frac{4!26!}{2!2!3!23!}\times \frac{5!25!}{30!}\\ =\frac{24*25*26}{1}\times \frac{2*3*4*5}{26*27*28*29*30}\\ =\frac{6*5}{1}\times \frac{2*3*4*5}{27*7*29*6}\\ =\frac{5}{1}\times \frac{2*4*5}{9*7*29}\\ = \frac{200}{1827}\\ \)
I have not checked my working.
