I get C. If I see this on the test, id prolly get to 210 and then guess A B or C.
OK so for the first position we have only 2 possiblities ( proj manager) 3 for the team leader so and 7!/3!4! for the consultants
2*3*35 --> 210
Now I dunno how to figure out the constraints quickly but I eventually figured it out. Obvs. we want to figure out the total ways in which the two ARE on the same team.
I did it by AB are the two and XYZFN are the rest
ABXO (O stands for the other 4) So the first is ABXY, Z,F,N 4 possible choices
The next is
ABYO (but notice we already had YX so there are only 3 possible choices)
ABZO
ABFO
ABNO No possible here we used them all up
So 4+3+2+1 = 10
SO now its 2*3*10 =60
So 210-60 = 150
The correct answer is 26.56.
The diapers at the store would be $0.50 per diaper, online they would be $0.46 a diaper, so online is a better deal and you would save $0.04 a diaper.
