expression N = 9 + X + Y – Z , where X, Y and Z are variables representing
single digits (0 to 9). Alok would like to maximize N while Bhanu would like to
minimize it. Towards this end, Alok chooses a single digit number and Bhanu

15.Alice and Bob play the following coins-on-a-stack game. 20
coins are stacked one above the other. One of them is a special (gold) coin and
the rest are ordinary coins. The goal is to bring the gold coin to the top by
repeatedly moving the topmost coin to another position in the stack. Alice
starts and the players take turns. A turn consists of moving the coin on the
top to a position i below the top coin (0 ≤ i ≤ 20). We will call this an
i-move (thus a 0-move implies doing nothing). The proviso is that an i-move
cannot be repeated; for example once a player makes a 2-move, on subsequent
turns neither player can make a 2-move. If the gold coin happens to be on top
when it's a player's turn then the player wins the game. Initially, the gold
coin is the third coin from the top. Then
(a) In order to win, Alice’s first move should be a 0-move. (b) In order to
win, Alice’s first move should be a 1-move. (c) Alice has no winning strategy.
(d) In order to win, Alice’s first move can be a 0-move or a 1-move

Ghana and Bolivia, Ghana the stronger team has a probability of 2/3 of winning
the game. What is the probability that Paul will correctly pick the winner of
the Ghana-Bolivia game?

(b) 1/9
(c) 2/3
(d) 1/3
