If and are integers, then the geometric distribution is memoryless. However, since there are two types of geometric distribution (one starting at 0 and the other at 1), two types of definition for memoryless are needed in the integer case. If the definition is as above,

WebSep 18, 2009 · The geometric distribution is said to have the memoryless property P (X > x + n X > n) = P (X > x). The proof for the Type 1 Geometric distribution is shown in the ActEd notes Chapter 4 page 7. I assumed this could also be proved for the Type 2 distribution but, on attempting it, I get P (X > x + n X > n) = P (X > x – 1).
