Step-by-step explanation:
Total number of students = 15 + 10 = 25
Number of girls = 10
Number of ways to select 2 students =
Number of ways to select 2 girls =
Compute the probability of selecting two girls as follows:
Thus, the probability that both students are girls is 0.15.
0.15 simplified in fraction from: 3/20

I try
We have that
p^2−12p=13---------> p^2−12p-13=0<span>
using a graph tool--------> to calculate the quadratic equation
see the attached figure
the solutions are
p=-1
p=13 </span>
