SOLUTION: in how many ways can a four letter set of words be formed using the vowels, a,e,i,o,u, assuming that repetitions are allowed?
n = 5
r = 4
nCr = 5!/r!(n-r)!
5! = 120
4! = 24

Question 619244: in how many ways can a four letter set of words be formed using the vowels, a,e,i,o,u, assuming that repetitions are allowed?
n = 5
r = 4
nCr = 5!/r!(n-r)!
5! = 120
4! = 24
n-r = 1
nCr = 120/24*1 = 5
Is the problem with the 5?
