why sorry..

....it's not your fault because of I forgot math ..
my math understanding is probably not at any good level despite those years in a school, so I just do not understand odds in games that may have something like either
many rollovers or not an rollover option at all... because I usually look at how many JP winners there were, what is the price for one combination, and how good are all prizes...
From some reason, I really only can understand a game that has very rare rollovers, parimutuel prizes, % that these prizes hold, and game payout %... and from some reason, many people also may mainly understand odds in such a game(s), when such game(s) are offered
