I'm not a mathematician nor is this a mathematics question per se, instead it's a real life problem I need the solution for. I have three groups of different items let's say
Group 1: T-Shirt, Solid Shirt, Patterned Shirt
Group 2: Pants, Jeans
Group 3: Blazers, Jackets, Coats, Sweaters
I need to make a list of all possible unique combinations taking one item from each group. Is there a formula of doing it?
For instance: Tshirt + Pants + Sweaters; Solid Shirt + Jeans + Blazers
