Help please I will give Brainliest!!

12 * 0.7³

Step-by-step explanation:

1st doll: 12

2nd: 12 * 0.7

3rd: 12 * 0.7 * 0.7

4th (smallest): 12 * 0.7 *0.7 * 0.7 = 12 * 0.7³

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
