Suppose a student is selected at random from 100 students, 30 are taking Mechanical Engineering, 20 are taking Electrical Engineering and 10 are taking Mechanical and Electrical Engineering. Find the probability that the student is taking Electrical Engineering or Mechanical Engineering.

Suppose that a certain college class contains 39 students. Of these, 24 are seniors, 21 are mathematics majors, and 5 are neither. A student is selected at random from the class.(a) What is the probability that the student is both a senior and a mathematics major?(b) Given that the student selected is a senior, what is the probability that she is also a mathematics major?

An engineering school reports that 55% of its students were male (M), 40% of its students were between the ages of 18 and 20 (A), and that 25% were both male and between the ages of 18 and 20.What is the probability of a random student being male or between the ages of 18 and 20? 0.22 0.25 0.70 0.95

There are 40 students in a course: 15 freshmen, 8 sophomores, 12 juniors, and 5 seniors. One student is selected at random to attend a workshop and report back to the class. What is the probability that the chosen student is a junior? 12% 30% 40% 50%

In class X, 20% of the students are boys and 80% of them are girls. The probability that boys passed in mathematics is 0.5 and the probability that girls passed in mathematics is 0.10. One student is selected at random. What is the probability that the selected student is passed inmathematics?
