Considering that the expression 5a + 5a + 5ab + 5ab is equivalent to 10a + 10ab, what is an equivalent expression for 6abc + 6abc + 6abc?
a) 18abc
b) 18a + 18b + 18c
c) 18a + 18ab + 18abc
d) 216a + 216b + 216c

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
