Triangle abc underwent a sequence of transformations to give triangle a'b'c. which transformations could not have taken place?
a.
a reflection across the line y = x followed by a reflection across the line y = -x
b.
a reflection across the x-axis followed by a reflection across the y-axis
c.
a rotation 180° clockwise about the origin followed by a reflection across the line y = x
d.
a reflection across the y-axis followed by a reflection across the x-axis

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
