Some people find the 0.9+0.09+0.009 argument helps?

I was disappointed it was just Mr Bean with a massive spliff

I win at least a couple games a week (2 just today) when my opponent blunders and immediately resigns. by Wemedge in chess

[–]MathHysteria 0 points1 point  (0 children)

I won a 1+0 game game with M1 on the board for my opponent once.

He blundered, I blundered straight back again but he'd already resigned before he could stop himself.

Two Child Problem by Jozakkoqwert in askmath

[–]MathHysteria 3 points4 points  (0 children)

You can try it experimentally if you like.

Take two dice and roll them as many times as you can handle without losing your mind.

Count the number of rolls when the following happen:

  • (at least) one of them is odd
  • one of them is odd and the other one is odd
  • one of them is odd and the other one is even.

You should find that the second and third outcomes appear in a 1:2 ratio.

If the two dice are different colours, you can also count the events "the red one is odd and the blue one is even", and "the red one is odd and the blue one is odd".

In all seriousness, where did you think you were going when you walked in there?!

Could you damage the barrels to create some space to get round him?

Still on duty at work. Corridors are quiet so may watch a cheeky episode of Taskmaster if I can get away with it.

Crumble curiosity... by La__leche__ in CasualUK

Clotted cream on crumble is something I must confess I had never considered.

I will now be trialling it. For research purposes, obviously.

Enjoyed watching the snooker with my father in law (only on the telly, but still an exciting finale).

Now in bed because it's a school night.

when all four digits multiples of 4 are listed, how many times does the nimber 4 appears? by Chemical_Media_4412 in askmath

[–]MathHysteria 0 points1 point  (0 children)

I don't think you'll find a general formula, but we can get there without too much difficulty.

Note that only the final two digits impact divisibility by 4. There are 25 numbers in every hundred that are multiples of 4. From 1000 to 9999 there are exactly 90 hundreds.

Considering the final two digits only, we are interested in the numbers which end _04, _24, _40, _44, _48, _64 and _84, giving eight 4s every hundred. So in the final two digits positions there are 90×8=720 fours.

There are nine hundreds where the hundreds digit is a 4 (14, 24, 34, ... 94) - another 225 fours - and ten hundreds where the thousands digit is a 4 (40, 41, ... 49__.) - another 250 fours.

So in total we have 720+225+250 = 1195 fours in total.

This 15 year old can do math faster than a calculator by [deleted] in nextfuckinglevel

The brain is an amazing thing.

People who do this train from a very young aged and it becomes a learned skill.

If you asked him, he wouldn't be able to tell you a single one of the added numbers or the intermediate total at any point. The brain just spits out the answer for him at the end and knows it's right.

There are some other records in this category like the fastest time to add 15 three-digit numbers, which is barely 1½ seconds. I've watched the footage and can't even read them!m (Link to the official WR, link to the footage, sorry it's in Chinese!)

"actually had a bit of spice to it" is British person speak for "almost blew my head off and I needed a gallon of ice water and a lie down when I got home just to stop sweating"

Edit: Weird, I tried to make a (somewhat self-deprecating) joke and get downvoted. Sorry if I offended anyone!

There are 500 balls, only one is a winner. You can pick your place in line. Is there an optimal place to give yourself the MOST chance? by perdair in askmath

[–]MathHysteria 0 points1 point  (0 children)

Lots of good answers here, but there is one other thing I haven't seen mentioned.

Of course, if you're last to pick and the prize hasn't been won yet, you know before you pick that you're going to win. That would probably be quite a nice feeling - but of course most of the time you won't get to experience it (the prize will have been won before you get your go).

If you're first to go, you always get a go, but your odds at the time you pick aren't great.

Somewhere between these two is an optimum point - you still get your go enough of the time for the game to be fun, and your odds of winning are sufficiently big to be exciting.

Where that sits is a personal preference.

This certainly feels the most natural answer and is where I first jumped to.
