Homework Help Overview

The discussion revolves around a probability problem involving two trains, X and Y, arriving at a station randomly within a specified time frame. The trains stop for a duration of four minutes, and the problem asks for various probabilities related to their arrival times and whether they meet at the station.

Discussion Character

  • Conceptual clarification, Problem interpretation

Approaches and Questions Raised

  • Participants seek clarification on the specific probabilities being asked, particularly regarding the conditions under which the trains meet and the assumptions about their arrival times.

Discussion Status

There is an ongoing effort to clarify the original poster's questions, with some participants expressing confusion about the phrasing and intent of the problem. Suggestions to revisit the questions have been made, indicating a collaborative effort to understand the problem better.

Contextual Notes

Participants note the ambiguity in the original questions and the need for clearer definitions of the probabilities being requested. There is also mention of seeking further guidance from a lecturer, indicating that the problem may not have been fully understood in its current form.

Train X and Y arrive at a station at random between 8 am to 8.20 am trains stop 4 min assuming that the trains arrive independently.
1. Determine the probability the train X.
2. Determine the probability the train meet at the station.
3. Assuming that the trains meet; Determine the probability the trains arrive.

Please rewrite that so as to make sense. Also, what have you tried?

1. Determine the probability the train X.
Determine the probability that the train does what? Arrive at the station at a specific time?

2. Determine the probability the train meet at the station.
In other words that one arrives within four minutes of the other.

3. Assuming that the trains meet; Determine the probability the trains arrive.
?? You are given that the trains arrive! That probability is 1. That the trains arrive when?

Yes, you are. Take a deep breath, go back and read the questions again. I guarantee they are not what you wrote!
 
would like to help but i don't understand your question:confused:
 
Thank you for any reply. I got 5 question from my class. I also didn't get this question. I will go back to ask my lecturer about the question again.
