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
