In a class of 10, there are 2 students who forgot their lunch. if the teacher chooses 2 students, what is the probability that both of them forgot their lunch?

 The required probability is

Step-by-step explanation:  Given that in a class of 10, there are 2 students who forgot their lunch.

If the teacher chooses  2 students, we are to find the probability that both of them forgot their lunch.

Since there are two students who forgot their lunch, so the number of ways in which 2 students can be chosen from 2 students is given by

The number of ways in which 2 students can be chosen from 10 students is given by

Therefore, the probability that both the randomly chosen students forgot their lunch is

Thus, the required probability is
