1. James uses a 12-sided roller in a game. The sides of the roller are numbered 1 through 12. What is the probability of James
using the 12-sided roller to roll a 3 or a multiple of 3?
Mark only one oval.
5/12
1/12
1/4
1/3

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2

lol.

it's ok we all do this sometimes.

well in order to answer the question, you have to give us the dimensions of the prism first.
