The number of possible combinations of n people taken r at a time is:
.
n%21%2F%28r%21%28n-r%29%21%29
.
For students on committee:n=6; r=4
.
6%21%2F%284%21%286-4%29%21%29=6%2A5%2F%282%2A1%29=30%2F2=15 possible groups of students.
.
For teachers on committee: n=5; r=3
.
5%21%2F%283%21%285-3%29%21%29=5%2A4%2F%282%2A1%29=20%2F2=10 possible groups of teachers.
.
There are 15 different groupings of students and 10 different groupings of teachers, so total there are (15)*(10)=150 different committees possible
