Re: May I calculate the possibility ?<-One more

Hi Banana-san.

〉Hello, Moring. This is Banana. So long not to see you.
Yes I missed the last OHTEMACHI off-party.

〉〉I'm reading Oliver Twist by Dickens. And its style affects my writing style.
〉Ohhhhhhhh. Your comment! I wanted to get and read Oliver Twist.
I got it from Web (Virginia Univ. Library). Then it's free.
I want to watch the movie. And it will be end on this weekend at a movie theatre in my area. Then I'll go to theatre if I couln't finish to read it.

〉May I caliculate ?
Yes please.

〉1. You must catch the same train.
〉 The possibility is
〉 a)On Yamanote-sen, we can catch train in each two minites.
〉 b)It takes about one-hour for train to go round Yamanote-sen.
〉 c) 60minites / 2 minites/train = 30 trains
〉 So 30 trains runs on Yamanote-sen.
〉 d)When you get a train at random, the possibility is 1/30=3.3%
〉 to get certain train, which you got.
〉 So the possibility that you must catch the same train is 3.3%.
〉2. You must catch the same SHARYOU of the same train.
〉 a)I think, each train on Yamanote-sen has 10 SHARYOUs.
〉 b)So when you get the same train, the possibility that you get
〉 on the same SHARYOU is 10%.
〉 c)So the possibility that you got the same train and you got on
〉 the same SHARYOU is
〉 3.3% * 10% = 0.33%
〉3.Oh! I miss that Yamanote-sen has MIGIMAWARI and HIDARIMAWARI.
〉 It is 50%.
〉4.So THE POSSIBILITY is 0.167%(=0.33% * 50%)
〉 It is 1/60,000.
Thank you for trying fun things.
But I think you forgot one more thing.
I wrote "I got in the same car of the same train from the same door".
If one car have three doors at one side, the calculation is following:
THE POSSIBILITY = 1/30 * 1/10 * 1/2 * 1/3 = 1/1,800

Oh, this is bigger than your result of calcuration.
Did you made mistake or did I?

〉〉Thank you for reading!
〉〉Happy Reading & Writing.
〉〉See you.
〉〉Moring

〉Happy possibility 1/60,000!
〉See you in the Yamanote-sen train someday.

〉Banana
See you.
