Out of 100 students, two sections of 40 and 60 are formed. If you and your friend are among the 100 students, what is the probability that(a)        you both enter the same section?(b)        you both enter the different sections?

Explanation

To solve the problem step by step, we will calculate the probabilities for both parts of the question.
