Question: 1 / 400

If 100 students are enrolled in a physics course, with 60 math majors and 40 science majors, what is the chance that a randomly selected student, Sarah, is a science major?

60 percent

50 percent

40 percent

To determine the probability that a randomly selected student is a science major, you start by identifying the total number of students and the number of science majors. In this case, there are 100 students enrolled in total, with 40 of them being science majors.

The probability can be calculated using the formula:

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

In this scenario, the number of favorable outcomes is the 40 science majors, and the total number of outcomes is the 100 students. Therefore, the calculation would be:

Probability = 40 / 100 = 0.4

This equivalent value can also be expressed as a percentage by multiplying by 100, resulting in a 40% chance that the randomly selected student, Sarah, is a science major. Thus, the correct answer is the option representing 40 percent.
