Question

Drew has a bag of balloons that he is going to inflate for a party. He chooses a balloon from the bag, writes down the color, and places it back in the bag. He repeats this 80 times.
Drew calculates the relative frequency of each color balloon.

Outcome Purple Orange Yellow Green Blue
Relative frequency 0.09 0.13 0.11 0.25 0.43
Which statement about Drew's experiment is true?

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

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

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

Answer 1

The answer is D. The frequencies do not appear to be equally likely, so a uniform model is not accurate.

Answer 2

Relative frequency 0.09 0.13 0.11 0.25 0.43

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 Drew's experiment.
