Arggh! This counting methods thing is really getting to my head!!! PLEASE PLEASE PLEASE HELP ME!
1.) In how many ways can a hand of six cards be dealt from a pack of 52 cards?
For this question i drew up a diagram of 52 cars and 6 spots for the 6 cards. I reasoned that it probably is 6! but i was found to be incorrect, please correct me.
I don't quite understand the distinction between Permutations and Combinations, take this for example:
2.) Four runners are competing in a race, they are given respective tags of A,B,C and D. Only two prizes for the first and second racer will be distributed:
a.) Find the different combinations of winners. I found that it could be AB, AC, AD, BC,BD and CD But i don't quite understand how i got it, could someone please explain it to me.
b.) Find the combinations of the 1st and 2nd winners. Totally clueless for this one
