For a class activity, each student randomly chooses a number from one to ten. Which model shows the probability of choosing a number 4?

Answer 1

A fair way to represent the probability of choosing a number 4 in this scenario would be to use a bar graph with each number from 1 to 10 represented as a separate bar. Since there are 10 possible choices, the probability of choosing a number 4 would be 1/10, or 10%.

Here is a model in which each bar represents a number from 1 to 10, and the bar for number 4 is highlighted to show the probability of choosing it:

1) \| \| \| \| \| \| \| \| \| \| \| (4)

In this model, the highlighted bar represents the number 4, and since each student chooses a number randomly, the probability of choosing a number 4 is 1/10, or 10%.
