Let’s solve each question step by step.
We are told:
A fair die is tossed.
That means it’s a standard 6-sided die with numbers:
1, 2, 3, 4, 5, 6 — each equally likely.
Total possible outcomes =
6
Probability of an event = (Number of favorable outcomes) / (Total outcomes)
We’ll simplify fractions if needed.
---
1. What is the probability of rolling a 3?
Only one side has a 3 → favorable outcomes = 1
→ Probability =
1/6
---
2. What is the probability of rolling more than 4?
“More than 4” means:
5 or 6 → that’s 2 outcomes
→ Probability =
2/6 = 1/3
---
3. What is the probability of rolling less than 5?
“Less than 5” means:
1, 2, 3, 4 → that’s 4 outcomes
→ Probability =
4/6 = 2/3
---
4. What is the probability of rolling an even number?
Even numbers on a die:
2, 4, 6 → 3 outcomes
→ Probability =
3/6 = 1/2
---
5. What is the probability of rolling an odd number?
Odd numbers:
1, 3, 5 → 3 outcomes
→ Probability =
3/6 = 1/2
---
6. What is the probability of rolling a prime number?
Prime numbers between 1 and 6:
Remember:
1 is NOT prime (as noted in the image).
Primes:
2, 3, 5 → 3 outcomes
→ Probability =
3/6 = 1/2
*(Check: 2 is prime, 3 is prime, 5 is prime. 1 is not, 4 is not, 6 is not.)*

7. What is the probability of rolling a 3 or a 6?
Favorable:
3 or 6 → 2 outcomes
→ Probability =
2/6 = 1/3
---
8. What is the probability of rolling an even prime number?
What’s an even prime? Only
2 is both even AND prime.
(All other even numbers >2 are divisible by 2, so not prime.)
→ Favorable outcome: just
2 → 1 outcome
→ Probability =
1/6
---
Final Answer:
1. 1/6
2. 1/3
3. 2/3
4. 1/2
5. 1/2
6. 1/2
7. 1/3
8. 1/6
