Gommonitoimm Level 4 mmmmmm All of the level 1 = 3 people It will select 2 people from 2 groups from level 2 people Select 3 people from 2 groups from level 3 people ED It will select 4 people from 5 groups from level 4 people th 1. I need the mathematic formula to calculate this problem. 2. Show me in that formula how can I change the number of levels, the values of the levels and the number of people from each value I must be able to choose the number of people - the number of groups of people and the number of levels
