if you put all of the numbers together for the number of times the coins were tossed, you would get 200 total.
then you would add the numbers for the amount of times it came up heads, and you would get a total of 105.
so, out of 200 times, heads came up 105 times. put this into a fraction. 105/200.
now, multiply this fraction by 5 so that the total number of times the coin was tossed would be 1000. the fraction would not be 525 heads up/1000 times tossed.

hope this helped
