My friend and I play a game. Each of us starts with two coins, and we take turns tossing a coin. If it comes down heads, we keep it ourself; if tails, we give it to the other.

I always go first, and the game ends when one of us wins by having all four coins. If we play this game 1400 times, what is the expected number of games that I would win?

What is the least number of cards which could be on the table? How many of those would be Diamonds?

Some cards from an ordinary pack of playing cards were laid out on a table with face upwards. I thought of one card there, The KING OF HEARTS. I announced that I would tell Mr. A the value and Mr. B the suit of my chosen card. I whispered to Mr. A that I had chosen a KING and whispered to Mr. B that I had chosen a HEART. Their subsequent discussion went as below:

A: “I do not know the card that was chosen”

B: “I knew you would not”

A: “I still do not know the card, but at least I can now work out its colour”

B: “Now at last I can work out what card it is”

A: “So can I”
