In a blue jar there are red, white and green balls. The probability of drawing a red ball is 1/5. The probability of drawing a red ball, returning it, and then drawing a white ball is 1/10. What is the probability of drawing a white ball?

  1. 1/5.
  2. ½.
  3. 1/3.
  4. 3/10.
  5. ¼.

Answer(s): B

Explanation:

Indicate A as the probability of drawing a white ball from the jar. The probability of drawing a red ball is 1/5. The probability of drawing both events is 1/10 so, 1/5 x A = 1/10. Therefore, A = ½.



Out of a classroom of 6 boys and 4 girls the teacher picks a president for the student board, a vice president and a secretary. What is the probability that only girls will be elected?

  1. 8/125.
  2. 2/5.
  3. 1/30.
  4. 1/720.
  5. 13/48.

Answer(s): C

Explanation:

The basic principle of this question is that one person can’t be elected to more than one part, therefore when picking a person for a job the “inventory” of remaining people is growing smaller.
The probability of picking a girl for the first job is 4/10 = 2/5.
The probability of picking a girl for the second job is (4-1)/(10-1) = 3/9. The probability of picking a girl for the third job is (3-1)/(9-1) = 1/4.
The probability of all three events happening is: 2/5 x 3/9 x ¼ = 1/30.



Two dice are rolled. What is the probability the sum will be greater than 10?

  1. 1/9.
  2. 1/12.
  3. 5/36.
  4. 1/6.
  5. 1/5.

Answer(s): B

Explanation:

When rolling two dice, there are 36 possible pairs of results (6 x 6).
A sum greater than 10 can only be achieved with the following combinations: (6,6), (5,6), (6,5). Therefore, the probability is 3/36 = 1/12.



The numbers of pizza slices that are sold in Joey’s Pizza are only in quantities of 5 and 8 slices per customer. How many slices cannot be bought?

  1. 42.
  2. 33.
  3. 22.
  4. 20.
  5. 38.

Answer(s): C

Explanation:

Check every answer. 42 = 2 x 5 + 8 x 4.
33 = 5 x 5 + 8.
20 = 4 x 5.
38 = 5 x 6 +8.
The only a number which cannot be bought is 22.



Elizabeth is interested in dividing the rooms in the house among the family. Unfortunately, they do not divide equally. It turns out that in order for the rooms to be dividable, Elizabeth has to build two more rooms and kick out one of the family members. Which of the following can describe the number of the initial rooms in the house and the initial number of family members (in the order Rooms, family)?

  1. 20; 8.
  2. 30; 9.
  3. 15; 6.
  4. 10; 5.
  5. 22; 10.

Answer(s): B

Explanation:

First we can eliminate answers where the number of rooms can be divided by the number of people, such as answer D.
We are looking for an answer that if you subtract 1 from the right and add 2 to the left, the left number will be divisible by the right number.
The only answer that fits this description is B. (30 +2)/(8) = 4.
