Which box-and-whisker plot represents this data: 6, 7, 8, 10, 18, 20, 22, 25, 28, 28, 30, 30?

D

Step-by-step explanation:

Put this in statistics in my graphing calculator.

Min Value = 6

Max Value = 30

Q1 = 9

Median = 21

Q3 = 28

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

pls mark as brainliest
