Answer 2

Answer:

A) Flipping a coin and rolling a six sided dice.

Step-by-step explanation:

Lets use a process of elimination in order to find the correct answer.

We are looking for a uniform probability model. This means that every outcome in this situation has the same chance of occurring.

D) This cannot be the right answer as the chances of probability are $\frac{2}{5} ,\frac{2}{5} ,\frac{1}{5}$

As these are not all equal, this cannot be the right answer.

B) This cannot be the right answer as the chances of probability are $\frac{2}{5} ,\frac{3}{5}$

As these are not equal, this cannot be the right answer.

C) Lets look at every outcome that could occur in this situation.

You could have 2H, 2T, HT, and TH. As HT and TH are the same, their probability can be written together.

This means that the probabilities would be

$\frac{1}{4} ,\frac{1}{4} ,\frac{1}{2}$

This means that A must be the correct answer as we have ruled out every other option.
