One more for A
Initially I got 7 which was not one of the answer choices, then I had to read and re-read the question to understand it.

Another vote for A. I actually solve it by listing out all possible combinations: B=Blue, R=Red, Y=Yellow BBR, BBY, BRY, BRB Can anyone solve it by using formula or other intitutive method? :?:

ComplexVision · Answer

2 (prob of picking 1 out of 2 blues) * 2 (prob of picking 1 out of 2 reds) * 1 (yellow) = 4

20. In a flower shop, there are 5 different types of flowers. Two of the flowers are blue, two are red and one is yellow. In how many different combinations of different colors can a 3-flower garland be made?

a) 4.
b) 20.
c) 3.
d) 5.
e) 6.


At first thought .. Q asks about "different combinations of different". So should'nt it be 1? 1 blue, 1 red, 1 yellow

bqminh1983 · Answer

There are more than 1 i guess... I can only come up with listing them:

Y R B
Y R R
Y B B
B B R
B R R

So it's d) 5. 

Quite confident it's the rite answer but could someone give a more "systematic" answer? Like an aswer using C and A stuffs?

Yurik79 · Answer

I think its A 2*2*1=4

vipin7um · Answer

Agree. D is the right answer.

shevy · Answer

I am getting 4 as well

conocieur · Answer

the different combinations of different colors is a bit ambiguous, anyway
I would go with A

(y,r1,b1) (y,r1,b2) (y,r2,b1) (y,r2,b2)
