In Exercises 17鈥�20, refer to the accompanying table showing results from a Chembio test for hepatitis C among HIV-infected patients (based on data from a variety of sources).

False Positive Find the probability of selecting a subject with a positive test result, given that the subject does not have hepatitis C. Why is this case problematic for test subjects?

In Exercises 9鈥�20, use the data in the following table, which lists drive-thru order accuracy at popular fast food chains (data from a QSR Drive-Thru Study). Assume that orders are randomly selected from those included in the table.

Fast Food Drive-Thru Accuracy If one order is selected, find the probability of getting an order from 惭肠顿辞苍补濒诲鈥檚 or 奥别苍诲测鈥檚 or an order that is not accurate.

In Exercises 17鈥�20, refer to the accompanying table showing results from a Chembio test for hepatitis C among HIV-infected patients (based on data from a variety of sources).

False Negative Find the probability of selecting a subject with a negative test result, given that the subject has hepatitis C. What would be an unfavorable consequence of this error?

In Exercises 5鈥�36, express all probabilities as fractions.

Teed Off When four golfers are about to begin a game, they often toss a tee to randomly select the order in which they tee off. What is the probability that they tee off in alphabetical order by last name?

In Exercises 9鈥�20, use the data in the following table, which lists drive-thru order accuracy at popular fast food chains (data from a QSR Drive-Thru Study). Assume that orders are randomly selected from those included in the table.

Fast Food Drive-Thru Accuracy If one order is selected, find the probability of getting an order from Burger King or Taco Bell or an order that is accurate.

In Exercises 13鈥�20, express the indicated degree of likelihood as a probability value between 0 and 1.

Square Peg Sydney Smith wrote in 鈥淥n the Conduct of the Understanding鈥� that it is impossible to fit a square peg in a round hole.

In Exercises 9鈥�20, use the data in the following table, which lists drive-thru order accuracy at popular fast food chains (data from a QSR Drive-Thru Study). Assume that orders are randomly selected from those included in the table.

Probability Rewrite the following statement so that the likelihood of rain is expressed as a value between 0 and 1: 鈥淭he probability of rain today is 25%.鈥�

Notation When randomly selecting adults, let M denote the event of randomly selecting a male and let B denote the event of randomly selecting someone with blue eyes. What does $P\left(M|B\right)$represent? Is$P\left(M|B\right)$ the same as$P\left(B|M\right)$ ?

In Exercises 1鈥�10, use the data in the accompanying table and express all results in decimal form. (The data are from 鈥淢ortality Reduction with Air Bag and Seat Belt Use in Head-On Passenger Car Collisions,鈥� by Crandall, Olson, and Sklar, American Journal of Epidemiology, Vol. 153, No. 3.)
