Question

How many different three letters initials can people have​

Answer 1

Answer:

People can have 17,576 different letters initials.

Step-by-step explanation:

There are 26 letters in the alphabet.

We need to use product rule, because the first event is picking the first initial, the second event is picking the second initial and the third event is picking the third initial, also alphabets may repeat.

Product rule states that if one event can occur in m ways and second event can occur in n ways, the number of ways the event can occur in sequence is then m×n.

26 × 26 × 26 = 17,576

Thus, people can have 17,576 different three letter initials.
