every summer, each student organization at your school sends 2 students to summer camp. the teacher mentor randomly selects the students (pulls from a hat) the club has 10 students among the students is a set of twins. what is the probability the 2 slots will be filled by the twins? what is the probability neither twin will be selected?

<<what is the probability the 2 slots will be filled by the twins?>>
2/10 x 1/9 = 1/45
<<what is the probability neither twin will be selected?>>
8/10 x 7/9 = 28/45
