A fly has a lifespan of $4$–$6$ days. What is the probability that the fly will die at exactly $5$ days?
The solution given is "Here since the probabilities are continuous, the probabilities form a mass function. The probability of a certain event is calculated by finding the area under the curve for the given conditions. Here since we’re trying to calculate the probability of the fly dying at exactly 5 days – the area under the curve would be 0. Also to come to think of it, the probability if dying at exactly 5 days is impossible for us to even figure out since we cannot measure with infinite precision if it was exactly 5 days."
But I do not seem to understand the solution, can anyone help here ?
