Being the [im]probability of getting a double-six on two standard cubic dice.

40 (number of squares on a standard monopoly board)

Sorry, but I'm just trying to work out what a non-standard Monopoly board would look like. And anyway, I'd say there were only 4 squares on a Monopoly board. The rest of the spaces are rectangles. Of which there are 36. Well, 72 if you include the colour strips on the inside edge of each rectangle. And 74 if you include the spaces for the Chance and Community Chest cards.

Anyway, 225. That's the number squares on a Scrabble board.

9 (or really just 1) squares on a noughts and crosses board.

Forty-two!

Being the sum total of the number of spots on a pair of standard cubic dice...

(I don't know whether this property has anything at all to do with the Question to the Answer to Life the Universe & Everything - despite being a late-generation human-being from the 'planet' known as Earth.)

Also: please don't "dice" my brain!

204 - the number of squares on a chess board.

Of course, to get this you have to consider the 64 1x1 squares,
and the 49 2x2 squares, and the 36 3x3 squares, all the way up
to the 1 8x8 square.

The number of squares on an imaginary chess board for people who have strange number powers...

Heaven 17.

And that's a numberwang!

My mum has 4 kids, my dad has 5 kids, but in total we're 7 people (without mum and dad). How come?

Two of your mum's children, and two of your dad's children, are the same two children.

The other two of your mum's were not with your dad, as the other three
of your dad's were not with your mum.

And my number is: 2.0
