A die is thrown 20 times and the outcomes 1, 2, 3, 4, 5, 6 appear 4, 3, 3, 4, 4, 2 times respectively. What is the probability of getting a number less than 4?

Show answer

1/2

Step 1: Numbers less than 4 are 1, 2, and 3. Step 2: Their counts are 4, 3, and 3. Step 3: Total favourable outcomes = 4 + 3 + 3 = 10. Step 4: Total throws = 20. Step 5: Probability = 10/20 = 1/2.

A die is thrown 20 times and the outcomes 1, 2, 3, 4, 5, 6 appear 4, 3, 3, 4, 4, 2 times respectively. What is the probability of getting an even number?

Show answer

9/20

Step 1: Even numbers are 2, 4, and 6. Step 2: Their counts are 3, 4, and 2. Step 3: Total favourable outcomes = 3 + 4 + 2 = 9. Step 4: Total throws = 20. Step 5: Probability = 9/20.

A die is thrown 20 times and the outcomes 1, 2, 3, 4, 5, 6 appear 4, 3, 3, 4, 4, 2 times respectively. What is the probability of getting an odd number?

Show answer

11/20

Step 1: Odd numbers are 1, 3, and 5. Step 2: Their counts are 4, 3, and 4. Step 3: Total favourable outcomes = 4 + 3 + 4 = 11. Step 4: Total throws = 20. Step 5: Probability = 11/20.

4multiple choice

A coin is tossed 5 times and heads occur 3 times. In a second experiment, exactly one head out of 5 trials occurs 2 times. What is the probability of getting a head in the first experiment and exactly one head in the second experiment?

Show answer

3/5 and 2/5

Step 1: In the first experiment, head appears 3 times out of 5, so probability = 3/5. Step 2: In the second experiment, exactly one head occurs 2 times out of 5, so probability = 2/5. Step 3: The required pair is 3/5 and 2/5.
