CPU Usage
We have the hourly average CPU usage for a worker's computer over the course of a week. Each row of data represents a day of the week starting with Monday. Each column of data is an hour in the day starting with 0 being midnight.
Create a chart that shows the CPU usage over the week. You should be able to answer the following questions using the chart:
When does the worker typically take lunch?
Did the worker do work on the weekend?
On which weekday did the worker start working on their computer at the latest hour?
cpu_usage = [

Q3. (Dice Rolling) Write a program that simulates the rolling of two dice. The program
should use rand to roll the first die and should use rand again to roll the second die. The
sum of the two values should then be calculated. [Note: Each die can show an integer
value from 1 to 6, so the sum of the two values will vary from 2 to 12, with 7 being the
most frequent sum and 2 and 12 being the least frequent sums.] Figure 7.26 shows the 36
possible combinations of the two dice. Your program should roll the two dice 10,000
times. Use a one-dimensional array to tally the numbers of times each possible sum
appears. Print the results in a tabular format. Also, determine if the totals are reasonable
(i.e., there are six ways to roll a 7, so approximately one-sixth of all the rolls should be 7).

- Background: Game Rules The rules to the (dice) game of Pig: You will need 2 dice. To Play: a. The players each take turns rolling two die. b. A player scores the sum of the two dice thrown (unless the roll contains a 1): If a single number 1 is thrown on either die, the score for that whole turn is lost (referred to as “Pigged Out”). A 1 on both dice is scored as 25. c. During a single turn, a player may roll the dice as many times as they desire. The score for a single turn is the sum of the individual scores for each dice roll. d. The first player to reach the goal score wins unless a player scores higher subsequently in the same round. Therefore, everyone in the game must have the same number of turns.
