Suppose that I have a friend whose name is X. X has an elder brother who got married 10 years before. But X being a silly guy has the habit of forgetting things; you can say a “Short time memory loss”. This summer he is going to meet his brother after 10 years, and he has planned to purchase some clothes for his brother’s kids as a token of love. Each and every time he faces a problem he comes to me, so this time also, he came to seek help, and I have not left him empty handed. I told him that as far as I can recall, his brother has two children and one of them is boy who was born on a Tuesday. Now, it’s your turn to help him. What is the Probability that X's brother has two boys? Assume an equal chance of giving birth to either sex and an equal chance to giving birth on any day.
