Explanation / Answer

Binomial Distribution
PMF of B.D is = f ( k ) = ( n k ) p^k * ( 1- p) ^ n-k
Where   
k = number of successes in trials
n = is the number of independent trials
p = probability of success on each trial
P( X = 19 ) = ( 19 19 ) * ( 0.91^19) * ( 1 - 0.91 )^0
= 0.1666
it is n't unlikely that enough seats are avalible in airplane
