Asmall class has 10 students, 3 of whom are girls and 7 of whom are boys. the teacher is going to choose two of the students at random. what is the probability that the teacher will choose two boys? write your answer as a fraction in simplest form.

The probability that the teacher will choose a boy at random the first time is 7/10. After the first boy is picked, that leaves 9 people remaining, 3 girls and 6 boys, giving us a chance that a boy will be picked 6/9, or 2/3 of the time. We can multiply these fractions to give us the final chance two boys will be picked. 7/10 x 2/3 = 7/15 in simplest form.  The teacher will choose two boys 7/15 of the time.

Hi! Your answer is 7/15. Hoped I helped!
