36−a2

=

−2a4−3a3+54a2+108a+648

−a4+72a2−1296

=

(−a−6)(a−6)(2a2+3a+18)

(−a−6)(a−6)(a+6)(a−6)

=

2a2+3a+18

a2−36

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

happy to
