Scarlet has a box with 16 black pens and 8 red pens. the probability that a pen randomly picked from the box is a red pen is . scarlet uses a six-sided die to find the probability that each color of pen is picked. she assigns the numbers 1 and 4 on the die for red pens, and assigns 2, 3, 5, and 6 for black pens. using this simulation, the probability of picking a red pen is , and the simulation used is .

Number of black pens = 16

Number of red pens = 8

Total pens =

1. So, the probability that a pen randomly picked from the box is a red pen is :

2. She assigns the numbers 1 and 4 on the die for red pens, and assigns 2, 3, 5, and 6 for black pens. Using this simulation, the probability of picking a red pen is :

3. The simulation used is suitable.

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 "
