Problem Statement

Oliver is at a carnival. He is offered to play a game where he rolls a fair dice and receives $1\$1 if his roll is a 11 or 22, receives $2\$2 if his roll is a 33 or 44, and receives $3\$3 if his roll is a 55 or 66. Oliver plays the game repeatedly until he has received a total of at least $2\$2. What is the probability that he ends with $3\$3?
