Question

Among a group of students 50% of them like math, 40% of them like history and 10% both. What is the probability that a student randomly selected from the group likes nether math nor history?

Answer 1

Let the total number of students be 100.

So no of students who like math are 50

no of students who like history is 40

no of students who like both is 10.

So the probability of the students who likes neither math nor history will be 0.

hope it will help you.
