Question

Whole numbers are written on cards and then placed in a bag. Denzel randomly selects a single card, writes down the number, and then places it back in the bag. He repeats this 110 times.

Denzel calculates the relative frequency of each number card.

Outcome 1 2 3 4 5
Relative Frequency 0.23 0.41 0.09 0.13 0.15
Which statement about Denzel's experiment is true?

The outcomes appear to be equally likely, so a uniform probability model is a good model to represent probabilities in Denzel's experiment.

The outcomes do not appear to be equally likely, so a uniform probability model is a good model to represent probabilities in Denzel's experiment.

The outcomes appear to be equally likely, so a uniform probability model is not a good model to represent probabilities in Denzel's experiment.

The outcomes do not appear to be equally likely, so a uniform probability model is not a good model to represent probabilities in Denzel's experiment.

Answer 1

Which statement about Denzel's experiment is true?
(D) The outcomes do not appear to be equally likely, so a uniform probability model is not a good model to represent probabilities in Denzel's experiment.

Answer 2

Relative Frequency 0.23 0.41 0.09 0.13 0.15

So the outcomes do not appear to be equally likely.

Uniform model is only good for equally likely probabilities so it is not good here.

Correct ans is:

The outcomes do not appear to be equally likely, so a uniform probability model is not a good model to represent probabilities in Denzel's experiment.
