determain that a randomly selected person was born in december

Mr F says: (no. of days in Dec)/365

determain that a randomly selected person has a birthday on november 8

Mr F says: 1/365.

if you met someone and she asked you to guess her birthday are you likely to be correct

Mr F says: With a probability of 1/365 for a correct guess, what do you think ......?
