Answer: The odds of an event happening are the ratio of the number of ways the event can happen to the number of ways it cannot happen.
Odds = (probability of success) / (probability of failure)
In this case, the event is that a carton of eggs will have at least one cracked egg.
The probability of success (the event happening) is 2.5%
The probability of failure (the event not happening) is 100% - 2.5% = 97.5%
so we can find the odds by dividing the probability of success by the probability of failure.
Odds = 2.5 / 97.5 = 0.025/0.975 = 1/39
So the odds that a carton of eggs will have at least one cracked egg is 1:39, meaning that for every 39 cartons that are free of cracked eggs, one carton will have at least one cracked egg.
It means that it's 1 in 39 chance that a carton of eggs will have at least one cracked egg
