Circle X with a radius of 6 units and circle Y with a radius of
2 units are shown.
Which steps would prove the circles similar?
Translate the circles so they share a common center
point, and dilate circle Y by a scale factor of 4.
Translate the circles so the center of one circle rests on
the edge of the other circle, and dilate circle Y by a scale
factor of 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
