As we have learned

Theorem of Combinations

The number of ways of selecting none or more objects from a collection of m objects of one kind, n objects of another kind and p objects of another kind are (m + 1) (n + 1) (p + 1).

 

In this question,

 Number of ways = (5+1)(4+1)(3+1) = 6 \times 5 \times 4 = 120
