There are a lot of possible answers to this question. One would just be

first blank: 8

second blank: 4

Third blank: 1

Step-by-step explanation:

Basically mix and match numbers that would give you the same answer.

some other combinations:

9,0,1

7,8,1

6,12,1

5,16,1

4,20,1

3,24,1

2,28,1

1,32,1

( I think you could see a pattern here). If you want to change the last number, all you need to do is take some from the first blank

b

step-by-step explanation:

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
