Question

At a certain college, there were 700 science majors, 300 engineering majors, and 500 business majors. If one student was selected at random, the probability that the student is an engineering major is

Answer 1

The probability that the major of one student that is selected at random is engineering can be calculated by the total number of engineering major divided by the total number of students

p = engineering / total students
p = 300 / ( 300 + 700 + 500)
p = 0.2 is the probability of the major of one student is engineering
