Draw a number line. Make sure that the values -1 and 0 are on it. In between these two values, cut the interval into 5 equal slices. It doesn't have to be perfect. Just the general idea is what counts. Place your pencil at 0 and then count four spots to the left until you arrive at -4/5
Because a penny has two sides that is 50 percent and a cube 6 sides that's 16 percent. then you subtract 16 from 50 to get a 34 percent chance of probably.
