Total number of days in the year 1999 = 365
=> Possibility of either friend being born on 1 particular day = 1/365
∴ Possibility of both friends being born on that same 1 day
= 1/365*1/365
= 1/133225
=> Possibility of either friend being born on 1 particular day = 1/365
∴ Possibility of both friends being born on that same 1 day
= 1/365*1/365
= 1/133225
