(1) If A and B are equiprobable outcomes and |B|=100, explain using a Venn Diagram why P(A) <= P(B).

(2) Three indistinguishable (fair) dice are thrown simultaneously at random. Find the probability that the sum of the three dice is less than six and that no two dice show the same face (the same number.)

For (2), I get 0. Is this correct?

Not sure what to do for (1). Any help?
