Four biased coins, A, B, C and D are thrown. The probability that each coin will land on Heads is shown below:

Coin A 0.33
Coin B 0.033
Coin C 1/3
Coin D 30%

(a) Which coin is most unlikely to land on Heads?

(b) Which coin is most likely to land on Heads?

(c) Coin B is going to be thrown 4000 times.
Work out an estimate for the number of times coin B will land on Heads

In may you used 400 kilowatt-hours of energy for electricity. a. calculate the total electrical energy use in joules. b. calculate your average power use in watts. c. assume that your power supplier generates electricity by burning oil. note that 1 liter of oil releases 12 million joules of energy. how much oil is needed to generate the electricity you use? give your answer in both liters and gallons. a. the total electrical energy use was nothing _ joules. (type an integer or a decimal.) b. the average power use is nothing _ watts. (round to the nearest whole number as needed.) c. to generate the electricity you used, nothing _ l is needed. (round to the nearest whole number as needed.) to generate the electricity you used, nothing _ gal is needed. (round to two decimal places as needed.)
