Here' the answer to the question with detailed explanation. Write back in case you've doubts.
Possible values of difference of 2 dice is ?
A dice has 6 to 1 number.
2nd dice will also has 1 to 6 number.
The max width is when a dice has 6 and the other 1. The difference is 6-1 = 5
.The min width is when a dice has 1 and the other 6. The difference is 1-6 = -5. But since we are concerned with non negative numbers, out of -5,-4,-3, -2, -1, 0,1,2,3,4,5 we will only take non-negative numbers.
So, 0 to 5 are the possible numbers: 0,1,2,3,4,5

Suppose that 16 fair, 6-sided dice are rolled together (but independently). (a) What is the probability that the average face value (that is, after the roll, add the face values of all the dice together and then divide by 16) is between 3 and 4? (d) Let Y denote the total face value of the 16 dice after the roll. What is the mean and standard deviation of Y? (e) Now instead of rolling 16 dice, you roll n dice....

2. Assume two fair dice are rolled. Let X be the number showing on the first die and number showing on the second die. (a) Construct the matrix showing the joint probability mass function of the pair X,Y. (b) The pairs inside the matrix corresponding to a fixed value of X - Y form a straight line of entries inside the matrix. Draw those lines and use them to construct the probability mass function of the random variable X-Y- make...
