A tour operator has a bus that can accommodate 20 tourists. The operator knows that tourists may not show up, so he sells 21 tic
dalvyx [7]

Answer:

The expected revenue of the tour operator is 985.

Step-by-step explanation:

There are two outcomes:

Either less than 21 tourists show up and the operator does not have to pay anything. Or 21 tourists show up and the operator has to repay 100.

Anyways, initially he gets the price of all the tickets sold. That is 21 each at 50, so R = 21*50 = 1050.

Then, we need to find the probability that all of the 21 tourists show up. In this case, we have to subtract 100 from the revenue.

Each tourist has a 0.02 probability of not showing up. This means that each has a 1-0.02 = 0.98 probability of showing up. So the probability P that all 21 tourists show up is P = (0.98)^{21} = 0.6542.

So, the expected revenue of the tour operator is

R = 1050 - 100P = 1050 - 100(0.6542) = 984.58

Rounded up, the expected revenue of the tour operator is 985.

The graph below shows a household’s budget. If the household spends $2,000 a month, which of the following statements is not tru
andreev551 [17]
The THIRD statement is not true.
$2000 (spends a month)
The 5% of $2000 is only $100 for food.

The first statement is true "The household spend $260 per month on the car".
13 % of $2000 = $260

The second statement is true "The household spend $600 per month for rent".
30% of $2000 = $600

The fourth statement is also true "The household spend $200 in savings each month"
10% of $2000 = $200
