Alpha airlines' b777 planes have 16 business class seats in each plane. since cancellations and no-shows are quite likely, they have an overbooking policy i. e., they sell up to 18 business class tickets. for a given flight, suppose that 18 persons have purchased tickets, and each has a 20% chance of not showing up for the flight, in which case the full price of the ticket is refunded. in addition, suppose that the events that different persons do not show up for the flight are independent. a) compute using probability formulas: i) the probability that exactly all the 18 persons who purchased first class tickets show up for the flight. ii) the probability that at most 16 of the 18 persons who purchased first class tickets show up for the flight.

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.
