Ruth knows she has a 25% chance of having a child with blue eyes and a 75% chance of having a child with brown eyes. Ruth consid
ers making a spinner to simulate the probability of having three children with blue eyes. Describe what the spinner should look like and the steps she should take to perform the simulation.
There is two event that needs to be made: 1. blue eyes, and 2. brown eyes. A spinner is made with a circle. A full circle has 360 degrees and it would be divided based on the probability of the event. Blue eyes have 25% chance, so the angle of the spinner would be 25%*360°= 90° Brown eyes have 75% chance, so the angle of the spinner would be 25%*360°= 270°
So, the 90° of the circle would be written as 1(blue eyes) and 270° of the circle will be written as 2(brown eyes).
