Mr. rainer's car uses about 1.6 fluid ounces of gas per minute when the engine is idling. one night, he parked his car but forgot to turn off the motor. he had just filled his tank. his tank holds 12 gallons.
about how many hours will it take before his car runs out of gas?

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%
