2 1. Event A occurs with probability 0.2. Event B occurs with probability 0.8. If A and B are disjoint (mutually exclusive) then (i) p(A and B)=0.16 (ii) p(A or B)=1 (iii) p(A and B)=1 (iv) p(A or B)=0.16 2. Ignoring twins and other multiple births, assume babies born at a hospital are independent events with probability that a baby is a boy and that a baby is a girl both equal to 0.5. The probability that the next 5 babies are girls is: (i) 1 (ii) 2.5 (iii) 0.25 (iv) 0.03125 (v) 0.5

3 3. In a certain town 50% of the households own a cellular phone, 40% own a pager and 20% own both a cellular phone and a pager. The proportion of households that own neither a cellular phone nor a pager is (i) 10% (ii) 30% (iii) 70% (iv) 90% 4. Event A occurs with probability 0.3 and event B occurs with probability 0.4. If A and B are independent, we may conclude that (i) p(A and B)=0.12 (ii) p(A|B)=0.3 (iii) p(B|A)=0.4 (iv) all of the above
