Following frequency distribution shows the daily expenditure on milk of 30 households in a locality: daily expenditure on milk(in rs): 0-30,30-60,60-90,90-120,120-150 no. of households: 5,6,9,6,4

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
