In jar A there are 3 white balls and 2 green ones, in jar B there is one white ball and three green ones. A jar is randomly picked, what is the probability of picking up a white ball out of jar A?

  1. 2/5.
  2. 3/5.
  3. 3/10.
  4. 3/4
  5. 2/3.

Answer(s): C

Explanation:

The probability of picking the first jar is ½, the probability of picking up a white ball out of jar A Is 3/(3+2) = 3/5. The probability of both events is 1/2 x 3/5 = 3/10.



The probability of pulling a black ball out of a glass jar is 1/X. The probability of pulling a black ball out of a glass jar and breaking the jar is 1/Y. What is the probability of breaking the jar?

  1. 1/(XY).
  2. X/Y.
  3. Y/X.
  4. 1/(X+Y).
  5. 1/(X-Y).

Answer(s): B

Explanation:

Let Z be the probability of breaking the jar, therefore the probability of both events happening is Z x (1/X) = (1/ Y). Z = X/Y.



An ant walks an average of 500 meters in 12 minutes. A beetle walks 15% less distance at the same time on the average. Assuming the beetle walks at her regular rate, what is its speed in km/h?

  1. 2.215.
  2. 2.5.
  3. 2.775.
  4. 3.2.
  5. 3.5.

Answer(s): A

Explanation:

A beetle moves (0.85 x 500 = 425 meters) in 12 minutes that is equal to 0.425 Km in 1/5 of an hour. The speed in the right units is 0.425 x 5 = 2.125 Km/h.



A car was driving at 60 Km/h for 20 minutes, and then at 90Km/h for another 40 minutes. What was its average speed?

  1. 80.
  2. 75.
  3. 70.
  4. 65.
  5. 54.

Answer(s): A

Explanation:

The average speed is equal to: (Total distance)/(Total time) = (60 x 1/3 + 90 x 2/3)/1 = 80 Km/h.

The questions in the exam dumps are pretty same as the real exam the only problem is that it is not complete or has less questions compared to full version. I am from South Africa and this is expensive for me. So I will be using the free version.
