Question

Which device would NOT be helpful in simulating the chances of Ms. Sosa having a baby girl or baby boy?

A. A spinner with three equal parts
B. A 10-sided number cube
C. A coin
D. A 6-sided number cube

Answer 1

To simulate the chances of Ms. Sosa having a baby girl or baby boy, a device with two equally likely outcomes is needed. A coin, which only has two outcomes, would not be helpful in this simulation.

Step-by-step explanation:

In order to simulate the chances of Ms. Sosa having a baby girl or baby boy, we need a device that has two equally likely outcomes. A spinner with three equal parts, a 10-sided number cube, and a 6-sided number cube all have two possible outcomes (girl or boy) and would be helpful in simulating the chances. However, a coin only has two outcomes (heads or tails) and would not give us the desired simulation.
