Question from La, a student: Neglecting the effect of leap years, what is the chance that, of 6 people selected at random, 2 will have the same birthday? |
La,
The probability that two will have the same birthday is one minus the probability that they all have different birthdays. See if you can find the probability that they all have different birthdays.
