What does this mean?!?! I will mark brilliant

answer is D

Step-by-step explanation:

equilateral : having all its sides of the same length

isosceles acute : triangles are the triangles with all their internal angles being acute angles and only two sides equal to each other in length.

isosceles right : a right triangle that has of two equal length legs. Since the two legs of the right triangle are equal in length, the corresponding angles would also be the same

scalene acute : all sides have different lengths

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
