In reality, the distribution of birthdays in a roomful of people can be somewhat uneven. Suppose that a room contains n people born in the same year, and each person independently has probability pa ≈ 0.003 of being born on any one of the 260 weekdays of that year, and probability pb ≈ 0.002 of being born on any one of the 105 weekend days.2 Give an expression for the probability that at least one pair of people in that room share a birthday.
