If a die is thrown, what is the probability of occurrence of a number greater than 1 if it is known that only odd numbers can come up ?

The correct Answer is:
To solve the problem, we need to find the probability of rolling a number greater than 1 on a die, given that only odd numbers can come up. ### Step-by-Step Solution: 1. **Identify the Sample Space**: When a die is thrown, the possible outcomes are {1, 2, 3, 4, 5, 6}. However, since we are told that only odd numbers can come up, we need to restrict our sample space to the odd numbers. - **Sample Space (S)**: {1, 3, 5} 2. **Determine the Favorable Outcomes**: We need to find the outcomes that are greater than 1 from our restricted sample space. The numbers greater than 1 in our sample space {1, 3, 5} are {3, 5}. - **Favorable Outcomes (F)**: {3, 5} 3. **Count the Outcomes**: - The total number of outcomes in the sample space (S) is 3 (which are 1, 3, and 5). - The total number of favorable outcomes (F) is 2 (which are 3 and 5). 4. **Calculate the Probability**: The probability (P) of an event is given by the formula: \[ P(E) = \frac{\text{Number of Favorable Outcomes}}{\text{Total Number of Outcomes}} \] Substituting the values we found: \[ P(\text{number greater than 1}) = \frac{2}{3} \] ### Final Answer: The probability of rolling a number greater than 1, given that only odd numbers can come up, is \(\frac{2}{3}\). ---
