You have a container with balls numbered between 1 and 20, if you randomly draw a ball from the container, what is the probability that the number on the ball will be divisible by 4 or will have a value three through 9?

3 / 5

Step-by-step explanation:

Numbers divisible by 4: {4, 8, 12, 16, 20}

Values 3 through 9: {3, 4, 5, 6, 7, 8, 9}

In probability "or" means addition (+)

Therefore:

Prob. (no divisible by 4 or value 3 through 9) =

5 / 20 + 7 / 20

= 5 + 7 / 20

= 12 / 20

= 3 / 5.

a net is a diagram that shows a “flattened” view of a solid. in a net, each face and base is shown with all of its dimensions. a net can also serve as a pattern to build a three-dimensional solid.

a pyramid is a three-dimensional object with a base that is a polygon and triangular faces that meet at one vertex.

" the net of a triangular pyramid consists of four triangles. the base here we are given of the pyramid is a equilateral   triangle, and the lateral faces are also triangles "
