The number of ways he can distribute 4 ones into 5 groups is 120 ways.
Permutation
Permutation has to do with the arrangement. For instance, to distribute "r" values into "n" groups, this can be calculated as:
Hence for you to distribute 4 ones into 5 groups, we will use the formula above to have:
5P4 = 5!/(5-4)!
5P4 = 5!/1!
5P4 = 5!
5P4 =120 ways
Hence the number of ways he can distribute 4 ones into 5 groups is 120 ways.
