For a special operations air assualt mission, one extra soldier for the security element is to be chosen at random from among three soldiers from the 327th Infantry Regiment, two soldiers from the 502nd Infantry Regiment, and five soldiers from the 187th Infantry Regiment.

- A. 1/10
- B. 3/10
- C. 3/7
- D. 1/3
正解：B
解説：
The probability of an event occurring is the number of "favorable'' outcomes divided by the total possible number of outcomes. Since there are three soldiers from the 327th from which to choose, there are three possible favorable outcomes for choosing a soldier from that unit. Since the choice will be made from among a total of 10 soldiers, there are 10 different possible outcomes. The probability of choosing a soldier from the 327th Infantry Regiment is 3/10.

質問 # 498
Any discussion of distinctive military capabilities would be incomplete without looking at their relationship to the Joint Service vision of the future. JV 2020 guides all the Services into the next century with its vision of future war fighting. JV 2020 sets forth four overarching operational concepts:
dominant maneuver, precision engagement, focused logistics, and full-dimensional protection. Each of these operational concepts reinforces the others. The aggregate of these four concepts, along with their interaction with information superiority and innovation, allows joint forces to dominate the full range of military operations from humanitarian assistance through peace operations to the highest intensity conflict.

質問 # 503
If a train can travel 500 miles in five hours, how far can it travel in 15 minutes?
- A. 57 miles
- B. 30 miles
- C. 125 miles
- D. 25 miles

質問 # 507
There are 12 liters of a mixture of acetone in alcohol that is 33 % acetone. 1 low many liters of alcohol must be added to the mixture to reduce it to a mixture containing 25% acetone?
- A. 0
- B. 1
- C. 2
- D. 3
正解：D
解説：
If the original mixture is 33 % (or 1/3) acetone, then 1/3 of the mixture of 12 liters, or 4 liters, is acetone.
The fraction 4/12 represents the ratio of acetone to total mixture. If the total mixture is increased by x liters, the ratio of acetone to total mixture becomes 4/(12+x).This is to be equal to 25% (or 1/4).
4 / 12+x = 1 / 4
To undo the divisions on both sides of the equation, multiply both sides by 4 and also by 12+x.
4/12+x * 4(12+x)/1
= 1/4 * 4(12+x)/1
16 = 12+x
The isolate x on one side of the equation, subtract 12 from both sides 16-12 = 12 + x-12 4=x

質問 # 510
The base of a cylindrical can is a circle whose diameter is 2 inches. Its height is 7 inches. How many cubic inches are there in the volume of the can? (Use 22/7 for the value of n).
- A. 0
- B. 1
- C. 124/7
- D. 2
正解：B
解説：
The volume of a cylinder is equal to the product of its height and the area of its base. The base is a circle.
The area of a circle is r2, where = 22 / 7 andris the radius. Since the diameter is 2 inches, the radius (which is one-half the diameter) is I inch.
Area of circular base =
22/7 x 1/1 x 1 / 1 = 22 / 7
The height is 7 inches.
22 / 7 x 7 / 1 = 22 cubic inches
