The odds against an event is a ratio of the probability that the event will fail to occur (failure) to the probability that the event will occur (success).
Odds against event = P(failure) / P(success)
P(success) = 2/7
P(failure) = 1 - P(success)
P(failure) = 1 - 2/7
P(failure) = 5/7
Odds against event = (5/7)/ (2/7)
Odds against event = 5/2
the odds against selecting a can of juice are 5 : 2.
