What are the odds of someone having the same initials?

Question

26 letters A-Z. How many different 3 letter combos are there?

Answer 1

The calculation would have to take into account the frequency of usage of the letters involved. The likelihood of ABC being duplicated is far greater than XYZ. I couldn't be bothered to take it that far, but maybe someone would.

Answer 2

What are the odds of two sisters in law having the same name? My sister in law and I are both named Shannon and we have the same married last name. Pretty ironic.

Answer 3

Look At How Many People There Are In The World, So It Could Happen Even A Couple Of Times I Guess.

Answer 4

Probably quite common  but remember the names would be different  good question too

Answer 5

There are 26 possibilities for each initial - so the number of possible 3-initial combos is 26 x 26 x 26, or 17,576.

The odds of someone having the same 3 initials as someone else are 1 in 17,576.

The odds of someone having the same 2 initials as someone else are 1 in 676.

Answer 6

351

Answer 7

About 1:1

Answer 8
