Questions
- A coin is tossed once. Find the probability of getting a head.
- A die is thrown once. Find the probability of getting 4.
- A die is thrown once. Find the probability of getting an even number.

- A card is drawn from a standard deck. Find the probability of getting a king.
- A card is drawn from a standard deck. Find the probability of getting a red card.
- A bag contains 5 red balls and 7 blue balls. Find the probability of drawing a red ball.
- A number is chosen from 1 to 20. Find the probability of choosing a prime number.
- If P(E) = 3/8, find P(not E).
- Can probability be greater than 1? Explain.
Answer key
Show suggested answers
- P(head) = 1/2.
- P(4) = 1/6.
- Even outcomes are 2, 4, 6, so probability = 3/6 = 1/2.
- Numbers greater than 4 are 5 and 6, so probability = 2/6 = 1/3.
- There are 4 kings in 52 cards, so probability = 4/52 = 1/13.
- There are 26 red cards in 52 cards, so probability = 26/52 = 1/2.
- Total balls = 12. Probability of red ball = 5/12.
- Prime numbers from 1 to 20 are 2, 3, 5, 7, 11, 13, 17, 19. Probability = 8/20 = 2/5.
- P(not E) = 1 - 3/8 = 5/8.
- No. Probability cannot be greater than 1 because favourable outcomes cannot exceed total outcomes.
