.

(a)  The event  (A or B) is this set  {1,2,4,6}.


      It consists  of 4 possible disjoint outcomes, each with the probability of  .

      Therefore,  P(A or B) =  = .      ANSWER




(b)  The event  (A and B) is this set  {2},  consisting of 1 (one)  outcome with the probability  .

      Therefore,  P(A and B) = .          ANSWER
