you are creating a model of the solar system and an asteroid that has a linear path that travels through it. The sun is at the center of the model and therefore will be placed at the origin (0,0). Using the scale of millions of kilometers to millimeters, the radius of select planets are as follows:

Suppose i flip two identical coins. what is the probability that i get one head and one tail?
