A sample question from this test
A fair coin is tossed 3 times. What is the probability of getting exactly 3 heads?
- 1/8
- 1/9
- 3/4
- 1/2
Answer: A. 1/8. Favourable outcomes = 1 out of 8, so the probability is 1/8.
How to approach this test
Permutation and Combination: Decide first whether order matters (permutation) or not (combination). Repeated letters divide the count by the factorial of each repeat.
Probability: Probability is favourable outcomes divided by total outcomes. Count both carefully and reduce the fraction at the end.
Clock Problems: The minute hand moves 6° a minute and the hour hand 0.5° a minute, so the angle at h:m is |30h − 5.5m|. Take the smaller angle if it exceeds 180°.
Calendar Problems: Count odd days: 7 days make a week, so only the remainder after dividing the number of days by 7 shifts the weekday.
This set leans easy, so use it to confirm that you can solve the basic pattern accurately before you move to harder sets. At 25 questions in 35 minutes, you have about 84 seconds per question on average. After you submit, review every wrong or guessed answer using the explanations.
