A marketing survey compiled data on the number of cars in households.  If X = the number of cars in a randomly selected household, and we omit the rare cases of more than 5 cars, then X has the following probability distribution: 
X           0          1          2          3         4         5    

P(X)   0.24    0.37    0.20    0.11    0.05      0.03
What is the probability that a randomly chosen household has at least two cars?
