Answer 3

Calculating the Probability of Naming a Multiple of 15

To calculate the probability of a student naming a number between 1 and 100 that is a multiple of 15, we need to determine the total number of multiples of 15 within this range and then divide it by the total number of integers in the range.

Total Multiples of 15 in the Range of 1 to 100: The multiples of 15 within the range of 1 to 100 are 15, 30, 45, 60, 75, and 90.

Total Number of Integers in the Range of 1 to 100: There are 100 integers in the range of 1 to 100.

Calculating the Probability

The probability of the student naming a multiple of 15 can be calculated using the formula:

Probability = (Number of favorable outcomes) / (Total number of possible outcomes)

Substituting the values: Probability = (6) / (100) = 0.06

Therefore, the probability of the student naming a multiple of 15 is 0.06 or 6%.
