Committe can be formed as
1 SP +2 JP
2 SP + 1 JP
3 Sp

So selction is possible in
4C1*6C2 + 4C2*6C1+ 4C3 ways. So total 60+36+4 = 100 ways.

Total outcome 10C3 = 120
groups only consist of junior partners 6C3 = 20

Thus, 120-20 = 100

3 ways of forming the group

1S + 2J: 4c1x6c2=60
2S + 1J: 4c2x6c1=36
3S +0J: 4c3=4
total =60+36+4=100
