Series circuits have the components on the same line and if any one fails, the entire circuit does not work (similar to old fashion Christmas lights). Consider the series circuit below with different colored lights. The probability that a bulb fails during the holiday season varies by color with P(failure for red) = $probability ; P(failure for green)=0.60; P(failure for blue) = 0.70. Each bulb fails independently of the other bulbs.

[CJS1]Dynamic. Vary between 0.30 to 0.50 by 0.05. Don’t let two entries be “symmetric” about 0.5 because then some of the answers below will be duplicates.

The table below shows the number of passengers carried by various airlines on domestic flights into or out of the Atlanta Airport during $month 2012. The five airlines with the most passengers are shown separately, and all other airlines are combined.

Airline Number of Passengers

American Airlines $AmericanAirlinesPassengers
Delta Air Lines $DeltaPassengers
Southwest Airlines $SouthwestPassengers
US Airways $UsAirwaysPassengers
All Others $AllOthersPassengers

Construct, interpret, and compare bar charts and pie charts to show the airline passenger data.
