Final answer:
In a uniform distribution, the probability of a patient waiting exactly a specific time, like 50 minutes, is 0 because the distribution is continuous.
Step-by-step explanation:
The probability of a patient waiting exactly 50 minutes in a uniformly distributed time to see a doctor, which ranges from 35 minutes to 2 hours (120 minutes), is 0. This is because in a continuous uniform distribution, the probability of the variable taking on any single, specific value is zero, since there are an infinite number of possible values it could take on within the range. However, we can calculate probabilities over intervals of time.
