Probability yet again

Two players of equal skill, A and B, are playing a set of games; they leave off playing when A wants 3 points and B wants 2. If the stake is Rs. 16, what share ought each to take?

You have not explained if the poits are +1, 0 or +1, -1

that will make a huge diference..

What you will probably need is a recurrence relation/...

hmm.. then i have no idea of what is there in their mind

this is a question of random walk.. (evne though you should not worry too much about hte word)

but i think they have not specified somethign or i have no clue of what the question is :(

This is not at all my original solution. It is a copied one.

A win may in the following manner:-

1) W W W
2) W W L W
3) W L W W
4) L W W W

P(A)= 1/8 + 3c1(1/2)(1/2)2(1/2)

=1/8 + 3/16
=5/16

P(B)= 11/16

A gets 5/16 *16 Rs. =5
B gets 11/16 *16 Rs. =11

no injun.. if you are solving the modified question that i have given.. then you need to think more..

There will be recursion involved.
