You cannot POSSIBLY be asking one of us to sit here and roll a pair of dice 50 times and record the results. I have run into some very lazy students on this site in the past couple of years, but so far you are the world champion.

if you are asking for the expected results in experiements of rolling two dice in samples of 50, expected means what you would get if the 50 rollls were repeated many times. Compute the probability for each outcome of the pair of die.
2-- 1/36 outcome of dice (1,1)
3--2/36 outcome of dice (1,2) or (2,1)
etc
--
Then for each outcome multiply the probability by 50 and that would yield what you would ezpect in the "long" term. any given sample of 50 rolls might be different.
--
So for instance
2--- 1/36 50*(1/36)=50/36 you would expect on average 1.39 rolls summing to 2
3--- 2/36 50*(2/36)=50/18 you would expect on average 2.78 rolls summing to 3
etc
