(3/10)(2/10)(1/10)i think it'd be like 90

Look a this in the order your picking people:First person: 10 are availableSecond Person: 9 (one person has been selected out of the pool already)Third Person: 8Multiply the availability pools together: (10)*(9)*(8)=(720)720 possible groups of three could be selected.
