Question

You are playing a game that has two dice – one die has 6 sides numbered 1 through 6 and the second die has 8 sides numbered 1 through 8. A turn involves rolling both die together. Write Java code to play 1,000 turns and keep track of the sum of the two dice in each roll i.e, (2 through 14). When all 1,000 turns have been completed, print a formatted table showing the value of the sum of the two dice (2 through 14) and the number of times that value occurred.

        int[] counts = new int[EMPLOYEES];

        int countNeverTested = 0;

        int x;

        /For loop to be executed until a list of randomly

        selected employees who will be tested each

        week for the next 52 weeks/

**THE CODE SHOULD BE IN JAVA** Write an application that allows a user to enter any number of student quiz scores, as integers, until the user enters 99. If the score entered is less than 0 or more than 10, display Score must be between 10 and 0 and do not use the score. After all the scores have been entered, display the number of valid scores entered, the highest score, the lowest score, and the arithmetic average. An example of the program is shown below: Enter a score >> 6 Enter another score or 99 to quit >> 7 Enter another score or 99 to quit >> 9 Enter another score or 99 to quit >> 7 Enter another score or 99 to quit >> 99 4 valid scores were entered Highest was 9 Lowest was 6 Average was 7.25
