The objective is to determine the probability of obtaining a number less than or equal to 4 when a die is rolled. Step 1: Total Possible Outcomes A standard die has 6 possible outcomes: \( 1, 2, 3, 4, 5, 6 \). Step 2: Favorable Outcomes The outcomes meeting the condition (less than or equal to 4) are \( 1, 2, 3, 4 \). There are 4 such favorable outcomes. Step 3: Probability Calculation Probability is calculated as: \[ P(\text{Event}) = \frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}} \] Substituting the determined values: \[ P(\text{number} \leq 4) = \frac{4}{6} = \frac{2}{3} \] Answer: The probability of rolling a number less than or equal to 4 is \( \frac{2}{3} \).
