Mario's Rabbit Race Problem Description It's time for a game in Mario's world! Mario is up facing off against a big dragon in a rabbit race. There's a bag with A white rabbits and B black rabbits. Mario and the dragon take turns picking exactly one rabbit from the bag each time. Here's the tricky part: When the dragon picks a rabbit, it scares the others, and one rabbit randomly jumps out!

Note: Rabbits that jump out of the bag themselves are not considered to determine the winner.
