Please can you assist with the below

In a game you take a dice and you roll it. The dice is a 4 sided dice. Say you roll this dice twice. You win the game. If the outcome of the 2 rolls is m and m+1, or it is m+1 and m where m can be either a 1, 2 or a 3.

Suppose you pay $2 to play this game and you receive $4,50 for win.

Please calculate the Win percentage?

Thank you
