I wish I remembered high school statistics.

What’s the probability of getting a $1.00 on the big wheel?

No, I don’t mean landing on the 1.00 square. I already know the probability on that is 1/20.

For those who don’t know the “Price is Right”, to whiddle down the six contestants to two for the showoff, they have them spin a wheel with various values on them. In increments of 5 cents from 5 cents up to a dollar (spread in what appears randomly). You’re goal is to get closest to a dollar without going over. You’re allowed to spin the wheel twice.

OK, lets say the person ahead of you has $0.95 on the board. Therefore the only way of getting to showdown *is* to get exactly. $1.00

What I do know.

The first spin determines if you have spin again. If you land on $1.00 (prob. 1/20) you win. If not (19/20) you spin again. (Your first spin could be considered your throw-a-way spin.) On the second spin, you’re chances of landing on the square that will bring you’re total to a dollar is 1/20.

What I don’t remember is how to place those facts together into the overall probability of winning the big whell and moving on to the final round.

Thanks for the help.
