The birthday paradox is a veridical paradox: it seems wrong at first glance but is, in fact, true. While it may seem surprising that only 23 individuals are required to reach a 50% probability of a shared birthday, this result is made more intuitive by considering that the birthday comparisons will be made between every possible pair of ...
A study using the populations of Denmark and Austria (a total of 2,052,680 deaths over the time period) found that although people's life span tended to correlate with their month of birth, there was no consistent birthday effect, and people born in autumn or winter were more likely to die in the months further from their birthday.

If an ace is drawn from a deck and not reinserted, the next card drawn is less likely to be an ace and more likely to be of another rank. The probability of drawing another ace, assuming that it was the first card drawn and that there are no jokers , has decreased from 4 / 52 (7.69%) to 3 / 51 (5.88%), while the probability for ...
