# Statistics question help? watch

1. 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).
3. Hehe same here that is what i did so i assume im right then
