How can I calculate the sum for rolling a pair of dice
0
$begingroup$
I’ve been looking at this question and I’m pretty confused. I thought it meant that the tally was the amount of ways you can receive the sum. For example, to get a sum of 2, you can only get a (1,1) so that’s only one way. But I don’t know what the difference between that and “number of times” is. Am I missing something important?

A tally means he did this. He sat down, rolled the dice. Got a result and he made a check mark to keep track of his result. Then he rolled the dice again. He did this 14 times. And he got a 2 once, he didn't ever roll a 3, he rolled a 4 two times, and so on. Now if you sat down and rolled a dice 14 times you'll probably get different results because you are not John and you are doing this at a different time.

The question is simpler and more practical than you think. In this particular experiment a sum of $2$ happened one time, a sum of $3$ zero times, a sum of $4$ two times, and so on

Yea, this is just how many times John got those sums. You just have to write the equivalent number in the second column, i.e., 1, 0, 2, 1...

The difference between "tally" and "number of times" is that the "tally" is what you write down while you are doing the experiment and the "number of times" is what you write down as a final result after the experiment is done. It doesn't make sense to write down "1" the first time he gets a $4$ and then two cross it out and right down "2" the second time. So this is the sheet while he is in the middle of an experiment.

So the exercise is telling you to write down: $1,0,2,1,2,4,2,1,0,1,0$ the the last column.
