The answer to your question Roxannecalixto is decreases and produced.
Answer:
The probability that exactly 178 passengers will show up and causing a shortage of three seats is 0.004364
Explanation:
X = number of passengers show up
X follow binomial distribution with n = 180 ,
p = 1 - 0.05
= 0.95
P(X = 178) = binom.dist(178,180,0.95,0)
= 0.004364
Therefore, The probability that exactly 178 passengers will show up and causing a shortage of three seats is 0.004364
