Defining transformations
luka tried to define a rotation about point c.
. for the center point c, the image c' is at the same point as c.
• the distances between each pre-image and its image are all equal.
for a point p that is not at c, a counterclockwise rotation of about point c creates point p', such
that cp=cp and mzpcp = 0.
which counterexample shows that luka's definition does not define a rotation?

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

pls mark as brainliest

b, i believe, but not sure.
