Trouble counting odds

[StephenW]

hi, I am completely stuck as to an odds calculation, I bet on 2 in play sporting events, one with odds 1/16 and one with odds 1/6, both needless to say lost. Going by the odds I make it that the 1/16 was 94% and 1/6 was 86%,what is the probality that neither bet wins?
( I realize the bookmaker has got an edge on these odds but I am interested never the less)

Thanks
