A recent study showed that 50 percent of households in Syracuse have at least 2 cars. Let X denote a binomially distributed random variable that is the number of households that have at least 2 cars. Out of 16 randomly chosen households, what is the probability that exactly nine have at least 2 cars; at most six have at least 2 cars; anywhere from 8 to 12 have at least 2 cars?
