When he uses the compact car (resp. the minivan), he gets home before 5 : 30 p.m. 75% (resp. 60%) of the time. However, the minivan has air conditioning. Calculate the probability that:

a) he gets home before 5 : 30 p.m. on a given day;

b) he used the compact car if he did not get home before 5 : 30 p.m.;

c) he uses the minivan and he gets home after 5 : 30 p.m.;

d) he gets home before 5 : 30 p.m. on two (independent) consecutive days and he does not use the same vehicle on these two days.
