Suppose the 5 letters are A, B, C, D and E.
The letter A can either be in the combination or not: 2 options for A.
With each of these options, B can either be in the combination or not: 2 options for B - making 2*2 options so far.
With each of the options so far, C can either be in the combination or not: 2 options for C - making 2*2*2 options so far.
and so on.
So for 5 letters there are 25 = 32 combinations. However, one of these is the combination that excludes each of the 5 letters - ie the null combination. Excluding the null combination gives the final answer of 31 combinations.

To find the number of four-letter words that can be created from the letters in "olvge," we first note that there are 5 unique letters. We can choose 4 letters from these 5 in ( \binom{5}{4} = 5 ) ways. Each selection of 4 letters can be arranged in ( 4! = 24 ) different ways. Therefore, the total number of four-letter combinations is ( 5 \times 24 = 120 ).
