Question

Whole numbers are written on cards and then placed in a bag. Pilar selects a single card, writes down the number, and then places it back in the bag. She repeats this 46 times.
Pilar calculates the relative frequency of each number card.

Outcome 1 2 3 4 5
Relative Frequency 0.05 0.35 0.26 0.13 0.21
Which statement about Pilar's experiment is true?


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

Answer 1

Answer:

The answer is A (i just took the test)

Step-by-step explanation:

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

The outcomes are: 1 2 3 4 5

The Relative Frequency: 0.05   0.35   0.26   0.13     0.21

As you can see the outcomes do not appear to be equally likely since 0.05 and 1 are not close in number range along with the other options

Answer 2

Answer:

Option 1  

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

Step-by-step explanation:

Given :

The outcomes are :             1         2         3        4        5

The Relative Frequency : 0.05   0.35   0.26   0.13    0.21

To find : Which statement about Pilar's experiment is true?

Solution :

We can see the outcomes do not appear to be equally likely.

Since 0.05 and 1 are not close in number range along with the other options.

So, The outcomes do not appear to be equally likely.

Uniform probability model - A model in which every outcome has equal probability.

But in given case, Probabilities in Pilar's experiment does not support a uniform probability model.

So, A uniform probability model is not a good model to represent probabilities in Pilar's experiment.

Therefore, Option 1 is correct.
