In a class of 8, there are 3 students who have done their homework. if the teacher chooses 2 students, what is the probability that both of them have done their homework?

Step-by-step explanation:

The probability that both of them have done their homework is .

Step-by-step explanation:

Consider the provided information.

In a class of 8, there are 3 students who have done their homework.

2 students chosen and we need to find the probability that both of them have done their homework.

The probability that first student have done their homework is:

The probability that second student have done their homework is:

Now the probability that both of them have done their homework is:

Hence, the probability that both of them have done their homework is .

correct answer is infinitely many solutions

step-by-step explanation:

2(2x + 3) = -4 + 2(2x + 5)

solving the above equation:

4x + 6 = -4 +4x +10

combining like terms

4x -4x = -4+10-6

0=0

since both sides are 0=0, we end up into true statement it means it has infinite many solutions.

so correct answer is infinitely many solutions
