In how many ways can set of five letters be selected from the english alphabet WITH SOLUTION .... THANKS
We have 26 letters and we want to choose any 5 of them.....this is given by the combination......
C(26,5) = 65,780 ways.... (different sets)
Have to make certain assumptions:
without replacement, order doesn't matter
The first letter can be selected from 26, the second from 25, etc
results in 7893600 combinations, I think.
