# Question

Exclude leap years from the following calculations and assume each birthday is equally likely:

(a) Determine the probability that a randomly selected person has a birthday on the 1st day of a month. Interpret this probability.

(b) Determine the probability that a randomly selected person has a birthday on the 31st day of a month. Interpret this probability.

(c) Determine the probability that a randomly selected person was born in December. Interpret this probability.

(d) Determine the probability that a randomly selected person has a birthday on November 8. Interpret this probability.

(e) If you just met somebody and she asked you to guess her birthday, are you likely to be correct?

(f ) Do you think it is appropriate to use the methods of classical probability to compute the probability that a person is born in December?
