  1. first of all, they asked for a probability.

    How many ways to seat all the people?

    Now, consider all the members of a class as one person. How many ways to seat them now?

    Do the same for the other classes.

    (Total ways to seat fused classes) divided by (total ways to seat everyone) is the probability.
