matt and ruba each have one coin.
The total amount of money is less than 50p.
work out the probability that exactly one of the coins is a 10p piece.
assume that all possible coins are equally likely.

  • MATHS -

    what's p?
    do the coins come in 1p by 1p or 10p by 10p? Not too sure about the coin system.

  • MATHS -

    the 50p is a 50p piece it says in the book it is less than 50p (money)

  • MATHS -

    sorry...... no idea. I mean it could be 49p, 49.99p, 49.999999p...?
    Do they come in whole numbers or what.
