Summary:: Bag A contains 1 white straw, 2 red straws and 2 green straws. Bag B contains 2 white
straws, 2 red straws and 1 green straw. One straw is drawn at random from each bag. Find the
probabilities that
(a) the two straws drawn are of the same colour;
(b) one straw is red and the other one is green.

I don't know if my answers are correct.

My answers are:
a. 1/5*2/5+2/5*2/5+1/5*2/5

b. 2/5*1/5+2/5*2/5

Correct, but please post homework problems in our homework section (I moved the thread).
You should probably evaluate these expressions for final answers.
