Points c,a,b are connected to form a triangle along the surface of a sphere. Points R,E,N are connected to form a triangle on a euclidean.
What is true between spherical and euclidean geometry?
You are given two dice to roll. One is black with six sides; the other is white with four sides.
For a given roll, what is the probability that the values of the dice add to 99?
