probability

[Progwolf]

Can someone explain what is the method to find the probability of drawing N specific cards in first hand?

I need to know what is the probability to draw al least 1 RoL and 1 Cremation in a 30 cards deck, within 6 RoL and 6 Cremations

30/6=1 in 5
first hand is 7 or 8 cards
i cant do the next bit i must be using wrong method sorry but 8 X 1 in 5 chances is the best i can do...
