Lol! We call our Social Studies teacher "The Thing". She has this deeper voice so usually we say she has this "thing".

@The Mighty Comrade
I'm doing grade 10 math, it's not a nightmare for me. Maybe I'm just good at it because I've done grade 9 math twice lol

Odds of first not semi: 11/17
Odds of second not semi: 10/16
...
Odds of sixth not semi: 6/12

Probability is 11/17*10/16*9/15*8/14*7/13*6/12
=11/7*5/8*3/5*4/7*7/13*1/2
=11/7*1/8*3/1*2/13
=66/728
~=.0907
= 9.07% Chance

Euler knows how to do it! Thanks man. But the question's really saying that the first 5 are non_semis, not the first six: since if you have to hand out six to *get* the semi you'd have 5 non-semi's and 1 semi. I got it wrong on the homework because of that >.<
