Probability is an easy and interesting mathematic subject. Here is a short and simple 'Probability multiple-choice quiz' with questions and answers given below. Try taking this test, and you'll get to practice your concepts. Probability, as we all know, is a measure of the likelihood that an event will occur. The higher the probability of an event, the more likely it is to occur, i.e., Tossing a coin gives a 50% chance of getting heads or tails. So, do you wish to take this test? Let's get started then.

If you rolled a 6-sided dice, what is the probability of rolling a 3?
- A.
1/6
- B.
2/3
- C.
3/6
- D.
5/6
Correct Answer
A. 1/6Explanation
The probability of rolling a 3 on a 6-sided dice is 1 out of 6 because there is only one face on the dice with the number 3, and there are a total of six possible outcomes when rolling the dice. Therefore, the chances of rolling a 3 are 1 out of 6 or 1/6.Rate this question:

If you flipped 2 coins, what is the probability that both will land on tails?
- A.
2/4
- B.
3/4
- C.
1/4
- D.
0/4
Correct Answer
C. 1/4Explanation
When flipping a coin, there are two possible outcomes: heads (H) or tails (T). For two coins, the possible outcomes are:
HH (heads, heads)
HT (heads, tails)
TH (tails, heads)
TT (tails, tails)
There are 4 possible outcomes in total. Only one of these outcomes is "both tails" (TT). Therefore, the probability of both coins landing on tails is the number of favorable outcomes (TT) divided by the total number of possible outcomes (4).Rate this question:

If you rolled a 6-sided dice, what is the probability of rolling a even number?
- A.
2/6
- B.
3/6
- C.
4/6
- D.
5/6
Correct Answer
B. 3/6Explanation
The probability of rolling an even number on a 6-sided dice can be calculated by dividing the number of favorable outcomes (rolling a 2, 4, or 6) by the total number of possible outcomes (rolling any number from 1 to 6). In this case, there are 3 favorable outcomes (2, 4, and 6) out of 6 possible outcomes, resulting in a probability of 3/6.Rate this question:

A lolly bag contains 2 red, 3 green and 2 blue gum balls. What is the probability of selecting a green one?
- A.
2/7
- B.
5/7
- C.
4/7
- D.
3/7
Correct Answer
D. 3/7Explanation
The probability of selecting a green gum ball can be calculated by dividing the number of green gum balls (3) by the total number of gum balls in the lolly bag (2 red + 3 green + 2 blue = 7). Therefore, the probability of selecting a green gum ball is 3/7.Rate this question:

A card is selected from a deck of playing cards. What is the probability of selecting a red card?
- A.
1/4
- B.
3/4
- C.
0/2
- D.
1/2
Correct Answer
D. 1/2Explanation
The probability of selecting a red card from a deck of playing cards is 1/2. This is because there are 26 red cards (13 hearts and 13 diamonds) out of a total of 52 cards in a deck. So the probability is calculated by dividing the number of favorable outcomes (red cards) by the total number of possible outcomes (all cards in the deck), which gives us 26/52 or 1/2.Rate this question:

What is the probability of selecting the diamond suit from a deck of playing cards?
- A.
1/4
- B.
2/4
- C.
3/4
- D.
0/4
Correct Answer
A. 1/4Explanation
In a standard deck of playing cards, there are 52 cards in total, and 13 of them are diamonds (since there are 13 cards in each suit).
To find the probability of selecting a diamond suit, divide the number of diamond cards by the total number of cards:
Probability = Number of diamond cards / Total number of cards Probability = 13 / 52 Probability = 1/4
So, the probability of selecting a diamond suit from a deck of playing cards is 1/4 or 0.25.Rate this question:
