2 square pyramids are connected at their base. The square base is 33 millimeters, and the height of the triangular sides are 28.6 millimeters. This 8-sided octahedron is a composite figure consisting of 2 square pyramids. The base of the pyramid is 33 mm, and the slant height is 28.6 mm. What is the surface area of the octahedron? mm2

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
