Explanation

According to the provided context, the ratio of the number of times an event occurs to the total number of trials is called the relative frequency (e.g., relative frequency of rolling a 4 is 8/50 = 0.16). Here, the number of students who like football is 15 out of a total of 50 students. Thus, the relative frequency is calculated as 15/50, which simplifies to 0.3.

Solution Steps

  1. Step 1: Identify the term for the ratio of observed occurrences to total trials, which is relative frequency.

  2. Step 2: Calculate the relative frequency using the formula: Relative frequency = (Number of students who like football) / (Total number of students) = 15 / 50 = 0.3.
