It doesn't make sense to me, because the longer you use it, the more likely it will break down. No?

In summary, the memorylessness property of waiting time refers to the independence of the probability of an event occurring within a certain time frame from any previous events. This concept has practical applications in various fields, such as queueing theory and telecommunications, and is mathematically represented by the exponential distribution. While it typically holds true, there are cases where waiting time may not be memoryless due to external factors. Understanding this property allows for efficient modeling and prediction of events and helps identify and address potential issues in systems involving waiting.

got it, thanks!

The memorylessness property refers to a characteristic of stochastic processes, where the probability of an event occurring within a certain time frame is independent of any previous events. In the context of waiting time, this means that the probability of an event occurring in the future is not influenced by how long we have already been waiting. This is because each waiting period is considered a new and separate event with its own probability, making the waiting time memoryless.

Memorylessness is a fundamental concept in stochastic processes that can be applied to many real-life situations. For example, the waiting time for a bus or train to arrive at a specific stop can be considered memoryless, as the probability of it arriving within a certain time frame is not affected by how long we have already been waiting. This property also applies to the waiting time for customers in a queue or the time between phone calls at a call center.

In mathematical terms, the memorylessness property is defined by the exponential distribution, where the probability of an event occurring in a given time interval is equal to the probability of that event occurring in any other equal time interval. This is known as the memorylessness property and can be mathematically represented by the equation P(X > t+s | X > s) = P(X > t), where X is the random variable representing the waiting time.

In some cases, waiting time may not exhibit the memorylessness property. This typically occurs when there are external factors that can influence the probability of an event occurring within a certain time frame. For example, if a bus is more likely to arrive within a specific time frame during rush hour, the waiting time for the bus would not be memoryless as it is affected by previous events (i.e. the time of day).

Understanding the memorylessness property of waiting time is important in various fields such as queueing theory, telecommunications, and finance. It allows for the accurate modeling and prediction of events that involve waiting, leading to more efficient processes and better decision-making. Additionally, this concept helps in identifying and addressing any potential issues or bottlenecks that may occur in systems that involve waiting.
