The correct Answer is:
To solve the problem step-by-step, we will calculate the probability of getting each specified outcome when a die is thrown 100 times. ### Step 1: Understand the Total Outcomes The total number of times the die is thrown is given as 100. ### Step 2: Find the Frequency of Each Outcome We need to find out how many times each number (1, 3, 4, 6) appeared in the 100 throws. According to the video transcript: - The number of times 3 appeared = 18 - The number of times 6 appeared = 9 - The number of times 4 appeared = 15 - The number of times 1 appeared = 21 ### Step 3: Calculate the Probability of Each Outcome The probability of an event is calculated using the formula: \[ \text{Probability} = \frac{\text{Number of favorable outcomes}}{\text{Total outcomes}} \] #### (i) Probability of getting a 3 - Number of times 3 appeared = 18 - Total outcomes = 100 \[ P(3) = \frac{18}{100} = \frac{9}{50} \] #### (ii) Probability of getting a 6 - Number of times 6 appeared = 9 - Total outcomes = 100 \[ P(6) = \frac{9}{100} \] #### (iii) Probability of getting a 4 - Number of times 4 appeared = 15 - Total outcomes = 100 \[ P(4) = \frac{15}{100} = \frac{3}{20} \] #### (iv) Probability of getting a 1 - Number of times 1 appeared = 21 - Total outcomes = 100 \[ P(1) = \frac{21}{100} \] ### Summary of Probabilities - Probability of getting a 3: \( \frac{9}{50} \) - Probability of getting a 6: \( \frac{9}{100} \) - Probability of getting a 4: \( \frac{3}{20} \) - Probability of getting a 1: \( \frac{21}{100} \)
