16. The sixteen thousand gasoline stations in Texas were tested on how accurate the consumers were being charged. The test found that 18% were overcharging the customer. Suppose that ten randomly selected Texas drivers are selected. a. (5 pts) What is the probability that exactly 3 out of 10 randomly selected Texas drivers will overpay for gasoline on their next trip to the station? b. (5 pts) How likely would it be that at least 6 of the 10 randomly selected customers are being overcharged?

Step 1
Step 1: To find the probability that exactly 3 out of 10 randomly selected Texas drivers will overpay for gasoline, we can use the binomial probability formula: P(x) = (n choose x) * (p^x) * (1-p)^(n-x) where n is the number of trials, x is the number of Show more…

Harry's Gas Station offers a discount of 5 cents per gallon of gas for customers who pay in cash. Past experience has shown that 30% of Harry's customers pay in cash. During a period of 30 minutes. 12 customers purchase gasoline. 1. What is the probability that at least 10 customers paid in cash?

Suppose the average price of gasoline for a city in the United States follows a continuous uniform distribution with a lower bound of $3.90 per gallon and an upper bound of $4.20 per gallon. What is the probability a randomly chosen gas station charges less than $4.05 per gallon? 0.333 0.500 0.804 0.300

David's gasoline station offers 4 cents off per liter if the customer pays in cash and does not use a credit card. Past evidence indicates that 40% of all customers pay in cash. During a one-hour period twenty-five customers buy gasoline at this station. What is the probability distribution that this experiment follows? What is the probability that at least five pay in cash? What is the probability that more than ten and less than fifteen customers pay in cash? What is the probability that at most three pay in cash? What is the expected value & standard deviation of the number of customers pay in cash?
