5. Suppose that the duration (in minutes) of telephone conversations over a 4G network is a contin- uous random variable X with probability density function fx(u) otherwise What is the probability that the duration of the conversation (a) will exceed 5 minutes? (b) will be less than 6 minutes? (c) will be between 5 and 6 minutes? (d) will be less than 6 minutes, given that it was greater than 5 minutes?
