Let us denote Y = students that suffer from math anxiety, N = students do not suffer from math anxiety.
Possible outcome : {YY, YN, NY, NN}
a. Both students suffer from math anxiety={YY} = $\frac{1}{4}$
b. Exactly one student suffers from math anxiety={YN, NY} =$\frac{2}{4}$
c. The first student does not suffer from math anxiety and second suffers from math anxiety={NY} =$\frac{1}{4}$
d. None of the students suffer from math anxiety={NN} =$\frac{1}{4}$

#### Work Step by Step
