    Hey guys

    Heres a quick question im not sure about whether i got the answer rright:

    Here it goes:

    There are 4 bottles of orange Juice. 3 Bottles of apple Juice, 2 bottle of tomato Juice.

    Viv takes a bottle at random and drinks the juice. Then Caroline takes a bottle at random and drinks the Juice.

    Work out the probability that they both take a bottle of the same type of Juice.


    The answer i came to was 20/72 but im not too sure if thats correct. If anyone can explain.


    Thanx

    regards

    I agree with that. You can, of course, cancel down that fraction.

    As to explanation, I did a probability tree; I only put on the branches that were relevant (don't ask me to draw it).
