Game odds at "The Price Is Right"

Factual Questions
1

Assuming no prior knowledge of product prices (e.g. you have no idea if the ravoili is higher or lower than $1.03, so it would be strictly 50/50 odds), what pricing games have the worst odds? Are there any games that have odds better than 50/50 (e.g. “Coming or Going” or “Switch?”)?

If you are in the audience at the beginning of any show, what are the best odds you can have for winning a car? The worst?

If the game you’ve been chosen for is Plinko, what is the calculated monetary odds you would win (i.e. a 30% chance of winning $100 = $30)? Would I be correct in assuming that the best spot to maximize winnings would be directly over the $0 slots?

Assuming, of course, that “Ten Chances” is still played. I haven’t seen the show in some time.
