An airline has a policy of booking as many as 15 persons on an airplane that can seat only 14. ​(Past studies have revealed that

only 88.0​% of the booked passengers actually arrive for the​ flight.) Find the probability that if the airline books 15 ​persons, not enough seats will be available. Is it unlikely for such an overbooking to​ occur?

Answer: No, it is unlikely for such an overbooking to occur.

Our required probability is 0.146.

Step-by-step explanation:

Since we have given that

Number of persons on an airplane book = 15

Probability of booked passengers actually arrive for the flight = 88%

We need to find the probability that if the airline books 15 persons, not enough seats will be available.

We will use "Binomial distribution":

Probability would be

P(X=15)=(0.88)^{15}=0.146

No, it is unlikely for such an overbooking to occur.

Hence, our required probability is 0.146.

Consider this figure of a hexagon.
notsponge [240]
A)
It looks like the [irregular] hexagon has 3 rectangles and 2 triangles within it.
So let's exclude the triangular corners on bottom left and top right for now.
First we have a large rectangle covering most of the upper left of the polygon. 20 ft × 7 ft = 140 sq.ft.
Now we have a rectangle on the bottom right. The width is 11 ft, so take the 7 away from that, 4 ft. × 14 ft. on bottom. 4 ft × 14 ft = 56 sq.ft.
The last small rectangle fits on the right between the 2 other rectangles. It is 24-20 on top/bottom × 7-6 right/left. 4 ft × 1 ft = 4 sq.ft.
Now for the triangles: bottom left is 11-7 × 24-14 = 4 ft × 10 ft. 1/2bh = 1/2×10×4 = 20 sq.ft.
Top right is 24-20 × 11-5 = 4 ft × 6 ft. 1/2bh = 1/2×4×6 = 12 sq.ft.

B)
Add them all together for the total area (A):
A = 140 + 56 + 4 + 20 + 12 = 140+60+32
= 232 sq.ft.

Hope that explains it well enough! ;)
