The least would be 950,000 and the minimum would be 900,000
This is combination problem since the order or arrangement matters. This is easily solvable with your scientific calculator. The formula would be nCr, where n is the total number of persons, and r is the number of persons in a group. So, using your calculator,
7C3 = 35
There can be 35 different groups.
