Two six sided dice are rolled one-thousand times, and the sums of the two dice are recorded. For example, if an 3 and a 4 are rolled, a sum of seven is recorded...sounds reasonable.
The results are in the table below. Based on this data, estimate the probability of getting a sum of seven the next time two dice are rolled.
So, we had a thousand rolls, and of the thousand rolls, how many times did we get a seven? Well, we got a seven 175 out of a thousand times!
So, 175 over 1000 seems like a pretty good estimate for the probability of getting a sum of seven the next time two dice are rolled.
So, 175/1000 , if we want to write it as a decimal, that would be one hundred and seventy-five thousandths, so we could write it as 0.175.
