Sovle: for n: 3xn =2x9

a: 2

b: 5
asap

c: 6

d: 8

e: 9

n will be 6

Step-by-step explanation:

3×n=2×9

substitute n=6 in the above equation

3×6=2×9

18=18

N is 6

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
