b. dot plots are best used to show answers to a non-statistical question.

A. Dot plots are best used to show a distribution of data.

Step-by-step explanation:

A dot plot is a used to display data using dots or we can also say it is a graphical display of data. This graph is used for relatively small data sets whose values are divided into small categories. So, the correct answer is -

A. Dot plots are best used to show a distribution of data.

(Options B, C and D are not true to the definition, hence these are wrong answers.)

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
