  4  -  7

   \     /

     -3

-3

Step-by-step explanation:

Follow P.E.M.D.A.S from left to right.

1. A: 2+2=4

2. S: 4-7=-3

percentage - 25%

probability - 0.25

we know,

total amount of students in class = 20

total boys = 10

total girls = 10

no of girls who wear glasses = 10/2 = 5

probability of choosing a girl with glasses is =

number of girls wearing glasses/total number of students in the class = 5/20

thus, percentage of selecting a girl wearing glasses will be

= 5/20 × 100

= 5 × 5

25%

therefore,

probability will be 0.25
