Question

Suppose each box of a popular brand of cereal contains a fidget spinner as a prize. The spinners come into options color changing or glow-in-the-dark.A.How could a number cube be used to simulate getting a color changing or glow in the dark spinner?B. How could a deck of cards be used to simulate getting a color changing or glow in the dark spinner?

Answer 1

The fidget spinner comes in 2 options: color-changing or glow in the dark.

So, it comes 50% probability of 1 option and 50% probability of the other

How do we use dice? We have to use it, but still, maintain the same probability for each outcome.

So, let's say if the dice outcome is 1, 3, or 5 it is color changing, if it is 2,4 or 6 it's glow in the dark. Why? Because the probability is= 3outcomes/6possible = 1/2 = 50%. It is the same.

For the cards, we can say that if the chosen card is a heart or diamond it is color changing and if it is a club or spades it glows in the dark. Why? In this case, the possible outcomes would be 2 out of 4, or 2/4=1/2=50%
