In a game, if you roll a 5 on a 6-sided number cube, you lose a turn. What is the probability that you roll a 5? Explain your re
WITCHER [35]
The probability of you rolling a 5 would be 1/6 since the cube has 6 sides and only one of the sides has a 5.

The probability that you either roll a 5 or do not roll a 5 would be 6/6 because 1/6, the probability you WILL roll a 5, and 5/6, the probability you WON'T roll a 5 added together is 6/6.

The probability that you don't roll a 5 is 5/6 because there are 5 sides of the dice that are not 5.

Answer:

156 inches^2

Step-by-step explanation:

The area of a triangle is 1/2 base x height

All of the triangles have a base of 6 inches and a height of 10 inches.

so 1/2 6 x 10= 30

There are 4 triangles with an area of 30 square inches

and then the square in the middle has a length of 6 in and a width of 6 in so it has an area of 36 in^2

so in total you would have 30+30+30+30+36, or 156
