Question

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

Part A
Ruth considers 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
Respond in the space provided
Part B
Ruth used a spinner to perform 10 trials to simulate the probability of having three children with blue eyes She observed 1 outcome of having three children with blue eyes.
• Is Ruth's estimated probability representative of the theoretical probability of having three children with blue eyes? Explain why or why not.
• Provide the estimated probability from Ruth's simulation and the theoretical probability of having three children with blue eyes
Respond in the space provided

Answer 1

Answer: I have no clue

Explanation: I don’t know

Answer 2

Answer: 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).
