Impossible to calculate such a probability. There is no reliable data on the number of different first names of people, not to mention the variations across different nationalities and ethnic groups. Then there is the added complication of same-sex marriages. If your instructor actually requires a specific answer to this problem, s/he has her/his head up her/his fundament.
