Two players each flip a fair coin. The probability that they get the same result can be expressed as ab where a and b are coprime positive integers. What is the value of a+b?
Dont get the a+b :(

You must be referring to your earlier post here

I had the probabily as 1/4
comparing this with a/b > a=1 and b=4
then a+b = 1+4 = 5
