Anna, Donna and Elena are college students and it’s time for the selection of the women’s hockey team. Anna and Elena are the only players who play as goal-keepers. Hence, exactly one of them has to be chosen. The chance of Anna being chosen is 40%.
(a) The chance of both Anna and Donna being chosen is 10%. What is the maximum and minimum chance of Donna being chosen?
(b) Suppose that the chance of Donna being chosen is 60% and that of both Donna and Anna being chosen is 20%. What is the chance that both Donna and Elena are chosen? What is the chance that Elena is chosen but Donna is not?
