PROBABILIDADE - EXERCÍCIO - RESOLUÇÃO EXATAS (APP) #8

In this video I solve an exponential probability distribution problem with conditional probability. Phone call times follow an exponential probability distribution with a mean of 3 minutes. A person walks up to a pay phone and finds that the person in front of him has been on the call for at least two minutes. What is the probability that this call will last at least five minutes in total?
