Find the GCF (Greatest Common Factor) of both numbers. It is 3.
Divide both numbers by the GCF.
The simplest form is 1/3.
Assuming a fair die,
probability of winning 0.25 = (2/6) = 1/3
probability of losing 0.25 = (4/6) = 2/3
Expected win
= sum (proba.*winning)
=0.25*(1/3) + (-0.25)(2/3)
=-0.25/3
= - (1/12) dollars (negative sign means expecting to lose)
He is, since each number is 4 more in value than the previous number
