A certain airline has $170$ seats available for a flight from YYC (Calgary International Airport) to LAX (Los Angeles International Airport). Because people with reservations do not show up for their flight $11\%$ of the time, the airline always overbooks this flight. That is, there are more passengers that have tickets on the flight than there are seats. 

Suppose the airline has $183$ passengers booked for $170$ seats. Assume one person showing up for the flight does not affect others who may, or may not, show up for this flight. 

When the flight takes off from YYC, what is the probability that there will be $6$ seats empty? Enter your answer to four decimals. 

$P(\text{$6$ seats empty})=$

I tried entering it in a software, but came up with the wrong answer. 
How would I approach this question?
