Probability and Statistics

Suppose a class of 30 students is to be divided into 4 separate groups,
as follows: 10 students in group A, seven in group B, six in group C, and seven in group D.
Suppose that Max and James are two particular students. What is the probability that they are both assigned to group B?

I was able to figure out that there were 3.996x10^15 possible arrangements of the groups
but I'm not sure how to assign the two particular students to a particular group. I got this by multiplying the choose functions for each group. as in (30 c 10)*(23 c 7)...etc
