a. a three-dimensional figure consisting of all points in space that are the same distance from a given point. this point is called the center of the sphere.
b. a three-dimensional solid consisting of two parallel congruent polygons and all the points between them
c. a three-dimensional solid consisting of two parallel congruent discs and all the points between them
d. a polyhedron that consists of a base, any point not in the same plane as the base, and all the points between them

the correct answer is

D. A polyhedron that consists of a base, any point not in the same plane as the base, and all the points between them

x = 25/2304

step-by-step explanation:

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
