What is the average range of this data?
6,9,3,5,4,2

a) 1.8
b) 2.2
c) 4.8

C) 4.8

Step-by-step explanation:

The average of a set is found by adding up all of the numbers, then dividing the sum over the number of numbers there are.

In this situation, that is (6 + 9 + 3 + 5 + 4 + 2)/6.

Simplifying gives us 29/6, which is equal to 4.8333..., or 4.8.

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
