Experience has shown that delivery takes longer than half an hour only 10 % 10%10, percent of the time. Let the random variable X XX be the pizza shop's profit for a randomly selected delivery order for one of these pizzas.

Answer:

$3

Step-by-step explanation:

The probability distribution for X, the pizza shop's profit is given below:

\left|\begin{array}{c|c|c}----&-----&----\\&$Late&$On-Time\\----&-----&----\\$X=Profit&-\$6&\$4\\----&-----&----\\P(X)&0.10&0.90\\----&-----&----\\\end{array}\right|

The mean of X is the expected value of X.

Mean, \mu=(0.10X-6)+(0.90X4)

=-0.6+3.6

=$3

The mean profit of the pizza's shop for a randomly selected delivery order for one of these pizzas is $3.
