Exercise 1 Page 777

We are asked to complete the following sentence.

A(n) for a particular random variable is a function that maps the sample to the probabilities of the outcomes of the sample space.

Let's recall that, using an equation, a frequency table or a frequency graph, we can show the probability distribution. This is a function that maps the sample space to the probabilities of the outcomes in the sample space for a particular random variable. Consider a box with ten balls of six colors.

box with balls

Next let's make a table showing the frequencies of drawing a certain color ball from our box.

Ball Color Frequency Probability
Green
Orange
Blue
Red
Purple
Yellow

Now we can make a graph of the probability distribution of this event.

Finally we will complete the given sentence.

A for a particular random variable is a function that maps the sample to the probabilities of the outcomes of the sample space.
