"Is it Estimated that 18% of the cars registered in the state cant meet the states new air pollution exhaust system standards. If there are 965,425 cars registered in the state, what is the average number of cars in the state that will not pass the new air pollution? what is the variance? What is the Standard deviation?

I have an 18 problem review packet and this is the only one that stumped me. Thanks in advance.
