From experience an airline knows that only 85% passengers
booked for a certain fly actually show up if 6 passengers are randomly selected find the probability that fewer than four of them show up

Step-by-step explanation:

Let's call p the probability that a passenger shows up.

Then we know that:

Then we took a sample of n = 6 passengers.

We can calculate the probability that less than 4 are presented using the binomial formula:

Where x is the number of passengers that show up, n is the number of selected passengers, p is the probability that a passenger shows up.

Then we look for:

point a is the center of the circle that passes through points e, f, and g and the center of the circle that passes through points x, y, and z.

the monthly balance will be $75,000
