Question

Assume that a gallon of milk bought at the store goes bad some time in the interval from 5 days to 10 days after purchase. What is the probability that it goes bad less than 4.5 days after purchase?

Answer 1

Unless it's a trick question that I don't understand, the probability of a time for milk to go bad to be less than 4.5 days is 0 because the assumption of a problem is that this time is always between 5 and 10 days after purchase.

The probability distribution looks like this (`P` - measure of probability, `T` - time the milk goes bad, numbers are days after purchase):
`P(T<5)=0`
`P(5<=T<=10)=1`
`P(T>10)=0`
