Answer

If out of 250 tosses, there are x heads, then the relation can be given as p = x/250 (where p is the proportion of head to tails) To calculate x, we have: x = p x 250 We have: x - 125 If out of 500 tosses, there are x heads, then the relation can be given as p = x/500 (where p is the proportion of head to tails) To calculate x, we have: x = p x 500 To determine the difference between x and 250, we have x - 250
