The stem and leaf display below represents the scores of a group of students in a test. The stem represents the tens part while the leaf represents the units part. Use it
to answer the questions that follow.

Stem. Leaves
2 4 1
3 3 2 3
4 1 5 4 7 5
5 2 3 8 1
6 2 3 1
7 4 3

(i) Construct a grouped frequency table using the class intervals 20 - 29, 30–39,
etc...
(ii) Draw a histogram for the distribution.
​

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

happy to

pls mark as brainliest

i belive the biggest ratio would be 18: correct me if im wrong
