If 85 percent of the autos arriving at the Lincoln Tunnel have either New York or New Jersey license plates, what is the probability that, of the next 20 autos, 2 or fewer (i.e., 0, 1, 2) will bear license plates from states other than New York or New Jersey?

Here is the answer I came up with...

0.667

The answer I came up with is incorrect. I used the 85% divided by 20 then multiplied the answer by 2

If possible, please help me.

Thanks,
