the probability that an RAC car is free to respond to an emergency is 0.8. Find the probability that, of two RAC cars on duty when an emergency call comes through
a- no car is available.::: 0.2^2 = 0.04
---------
b- both cars are available.::: 0.8^2 = 0.64
---------
c- just one car is available.:::0.8*0.2 = 0.16
---------
d- a car is available.:::: 1 - 0.04 = 0.96
