Question: A coin is tossed 8 times, what is the probability of getting exactly 7 heads ?
Answer: The total number of possible outcomes to toss a coin 8 times is 2^8=<power>(2,8)=256. The number of ways of getting exactly 7 heads is 8C7=<choose>(8,7)=8. The probability of getting exactly 7 heads is 8/256=<divide>(8,256)=0.03125. #### 0.03125

Question: If paint costs $3.2 per quart, and a quart covers 12 square feet, how much will it cost to paint the outside of a cube 10 feet on each edge?
Answer: The total surface area of the 10 ft cube is 6*10^2=6*<power>(10,2)=100=<multiply>(6,100)=600 square feet. The number of quarts needed is 600/12=<divide>(600,12)=50. The cost is 50*3.2=<multiply>(50,3.2)=160. #### 160

Question: log(x)=2, log(y)=0.1, what is the value of log(x-y) ?
Answer: log(x)=2, so x=10^2=<power>(10,2)=100; log(y)=0.1, so y=10^0.1=<power>(10,0.1)=1.26; x-y=100-1.26=<subtract>(10,1.26)=98.74, so log(x-y)=log(98.74)=<log>(98.74)=1.99. #### 1.99

Question: How many degrees does the hour hand travel when the clock goes 246 minutes?
Answer: The hour hand travels 360 degrees in 12 hours, so every hour it travels 360/12=<divide>(360,12)=30 degrees. 246 minutes is 246/60=<divide>(246,60)=4.1 hours. The hour hand travels 4.1*30=<multiply>(4.1,30)=123 degrees. #### 123
