Sample Questions
What is the probability of getting a number greater than 4 when rolling a dice?
Show answer
2/6
Numbers greater than 4 on a dice are 5 and 6. Number of favorable outcomes = 2. Total possible outcomes = 6. P(number > 4) = 2/6 = 1/3.
Which of the following are properties of probability? (Select all correct answers)
Show answer
Probability is always between 0 and 1, Probability of a sure event is 1, Probability of an impossible event is 0
The basic properties of probability are: (1) 0 ≤ P(E) ≤ 1 for any event E, (2) P(sure event) = 1, (3) P(impossible event) = 0. Probability cannot be negative or greater than 1.
A card is drawn from a well-shuffled deck of 52 cards. What is the probability of getting an ace?
Show answer
1/13
A standard deck has 52 cards with 4 aces (one in each suit). P(ace) = Number of aces / Total cards = 4/52 = 1/13. Note that 4/52 is mathematically equivalent to 1/13, but 1/13 is the simplified form.
Two coins are tossed together. What is the probability of getting at least one head?
Show answer
3/4
When two coins are tossed, possible outcomes are: HH, HT, TH, TT. Total outcomes = 4. Outcomes with at least one head: HH, HT, TH (3 outcomes). P(at least one head) = 3/4.
