I'm not very good at probability and I'm just having trouble interpreting and calculating what the questions actually want me to do. Could someone please help to explain this simply? 1.Five cards are dealt at random from a standard pack. Ignoring suit, what is the probability that at least two of them are the same? For this question I thought it was 1 - 13c5/52c5 = answer, but I'm not sure. 2. In a poker hand consisting of five cards dealt at random, what is the probability of a royal flush (Ten, Jack, Queen, King and Ace of the same suit)? No idea how to incorporate the different picture cards into this calculation. 3. In a variant of poker each player has seven cards. What is the probability of a royal flush in this case? I thought here it would just be 52c7 instead of 52c5 for all the possible samples, but I don't know where to go from there. I would really appreciate any help that can be given.
