    Posted By: Andrew PalfreymanC(50,5) = 1 in 2 million
    C(11,2) = 1 in 55
    Combined chance of a win = 1 in 116 million.


    Something's wrong. For example, two random-without-replacement choices from 11: first choice, eleven possible numbers. Second choice, ten possible numbers. 11 x 10 = 110

    Then we have, following the same pattern
    50x49x48x47x46=254,251,200
    and 254251200x110=27,967,632,000

    What am I doing wrong?

    I agree any 2 from 11 is 55

    10 and 11 over 1 and 2 =110/2 =55

    Yours is correct if the order matters.

    C(n,m) = n! / ( (n-m)! * m! )

    Ah yes, I see. Because there are two unique ways to draw a particular pair, if order isn't important.

    So there are 1x2x3x4x5= 120 different ways to draw a unique set of 5, again if order isn't important.

    So, 254,251,200 / 120 = 2,118,760 different ways to draw 5 from 50.

    Right?

    Random order applies.

    My Roo-bots are much more cuddly then these silly things.

    Softbank, Foxconn and Alibaba are joining to sell $1600 humanoid robots like Pepper.

    My roo-bots with their plus human brain could, of course they would have a brain implant that would make them adore humans and want to please them.

    If you could just skip the kangaroos and develop that for people it would be a step in the right direction.

    Forbidden I am afraid, just as well I suppose, imagine what would happen if I could control billions of beautiful women?

    Growing a placenta on a chip may help scientists develop an artificial womb that would allow mammals to be born without a biological mother.

    Even clones of Angus could be produced and sent hundreds of light years away or through a wormhole.

    You misunderstand. I mean that you should develop a technique to make all humans love all other humans and want to please them. A number of major religions have been founded on this fairly anodyne premise. Think of your upside if you can get market share!

    Just in thread so I won't notebook you this time.

    “koala cars” due to their marsupial-like appearance,

    Has anybody seen the BBC 'Kangaroo Dundee' about raising orphan joey's and then freeing them?

    It is on BBC Iplayer if anybody is interested.

    "we’ll have safety drivers aboard with a removable steering wheel, accelerator pedal, and brake pedal that allow them to take over driving if needed.", that's a lot of gear to carry about, just replace all that with an Xbox controller. :)
