Hey guys, today i came across this interesting problem and i think i should share it with all of you. Actually it's a rather FAMOUS puzzle which, i think, many of you heard about. It's called

THE MONTY HALL PROBLEM!

For the benefit of those who haven't heard about it and those who have heard about it but forgot what it was about, the problem goes like this:

In the 1960s, there was a popular weekly US television quiz show called Let's Make a Deal. Each week, at a certain point in the program, the host, Monty Hall, would present the contestant with three doors. Behind one door was a substantial prize; behind the others there was nothing. Monty asked the contestant to pick a door. Clearly, the chance of the contestant choosing the door with the prize was 1 in 3.

So far so good?

Now comes the twist. Instead of simply opening the chosen door to reveal what lay behind, Monty would open one of the two doors the contestant had not chosen, revealing that it did not hide the prize. (Since Monty knew where the prize was, he could always do this.) He then offered the contestant the opportunity of either sticking with their original choice of door, or else switching it for the other unopened door.

The question now is, does it make any difference to the contestant's chances of winning to switch, or might they just as well stick with the door they have already chosen?



Well, most people think that it makes no difference if they switch. Here is their reason:

"There are two unopened doors. The prize is behind one of them. The probability that it is behind the one I picked is 1/2, the probability that it is behind the one I didn't is also 1/2, so it makes no difference if I switch."


HOWEVER THAT EXPLAINATION IS WRONG!!
Why is it so??

Try to think about it before you look at the full and correct explaination here

The hint is "Switching actually DOUBLES the contestant's chance of winning"
Interesting??



Definitely!! Enjoy :D

Hi everybody
Are you all enjoying your holiday :)
I know there's a HUGE amount of homework to finish but at the same time, try not to forget the meaning of the word "HOLIDAY" okay =D
I've also uploaded the slides for last session here, if you have some free time you can just play around with your Mobius Band haha :D:D
Alright, remember to spend your holiday wisely okay, we'll see each other sooooon :D



*******************
Beauty of Maths

1 x 8 + 1 = 9
12 x 8 + 2 = 98
123 x 8 + 3 = 987
1234 x 8 + 4 = 9876
12345 x 8 + 5 = 98765
123456 x 8 + 6 = 987654
1234567 x 8 + 7 = 9876543
12345678 x 8 + 8 = 98765432
123456789 x 8 + 9 = 987654321

1 x 9 + 2 = 11
12 x 9 + 3 = 111
123 x 9 + 4 = 1111
1234 x 9 + 5 = 11111
12345 x 9 + 6 = 111111
123456 x 9 + 7 = 1111111
1234567 x 9 + 8 = 11111111
12345678 x 9 + 9 = 111111111
123456789 x 9 +10= 1111111111

9 x 9 + 7 = 88
98 x 9 + 6 = 888
987 x 9 + 5 = 8888
9876 x 9 + 4 = 88888
98765 x 9 + 3 = 888888
987654 x 9 + 2 = 8888888
9876543 x 9 + 1 = 88888888
98765432 x 9 + 0 = 888888888

Brilliant, isn't it?

And finally, take a look at this symmetry:

1 x 1 = 1
11 x 11 = 121
111 x 111 = 12321
1111 x 1111 = 1234321
11111 x 11111 = 123454321
111111 x 111111 = 12345654321
1111111 x 1111111 = 1234567654321
11111111 x 11111111 = 123456787654321
111111111 x 111111111 = 12345678987654321

Yes MATHS is really like that - Full of wonders.

You should also know the POWER OF 9.

Anything multiplied by 9 , it's sum total is 9.

For example, 62 * 9 = 558; 5 + 5 + 8 =18; 1+ 8 =9!
Just give it a try =)


Ever heard of this equation : e + 1 = 0 ?

It relates the five most fundamental constants in mathematics,

e and π are both transcendental and i is imaginary and yet they combine with 1 to make 0!

How wonderful <3

See ya all sooon :D

**********
For those who are very bored with all the regular Maths lessons we learn in school, here are something you may find interesting


Russell's paradox:
The set M is the set of all sets that do not contain themselves as members. Does M contain itself?



If it does, it is not a member of M according to the definition.
If it does not, then it has to be a member of M, again according to the definition of M.
Therefore, the statements "M is a member of M " and "M is not a member of M " both lead to contradictions.


So what's the answer to this question?
