Jillian wanted to determine the difference of 7 and a number, n. She wrote in a table several possible expressions she could use to represent this. Which is the correct expression number? Expression Number
Expression
1
n minus 7
2
7 minus n
3
7 n
4
StartFraction n Over 7 EndFraction

Expression number:

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
