Answer:
Answer is 0.9738
Step-by-step explanation:
Given, n == 125
Probability that passenger will not show up, q = 0.10
Probability that passenger will show up, p = 1 - q
= 1 - 0.10
= 0.9
The probability that the flight departs with empty seats.
μ = np ==> 125 x 0.9 ==> 112.5
σ = √npq ==> √125x0.9x0.1 ==> 3.354
∴ P( Z ≤ )
P ( Z ≤ 1.94 )
= 0.9738
