To Draw: The bar graph.

Answer to Problem 9WE
Explanation of Solution
Given:Find data suitable for presentation bar graph.
Suppose you survey of your friends what type of movies they like.
The data collected is as follows
Choose one axis for the members of the domain, say the horizontal axis. List the number of the range on the left along the vertical axis. For each member of the domain draw the vertical bar to represent the corresponding value in the range of the function. Start the scale of the bars at zero, so that their relative lengths are correct.
The bar graph is given as

(n - 1)!arrow_forwardAmy and Samiha have a hat that contains two playing cards, one ace and one king. They are playing a game where they randomly pick a card out of the hat four times, with replacement. Amy thinks that the probability of getting exactly two aces in four picks is equal to the probability of not getting exactly two aces in four picks. Samiha disagrees. She thinks that the probability of not getting exactly two aces is greater. The sample space of possible outcomes is listed below. A represents an ace, and K represents a king.
