WebFeb 13, 2013 · So we get E ( X) = ( 1 − p) ( 1 + E ( X)). That expands to ( 1 − p) + ( 1 − p) E ( X). We now have E ( X) = ( 1 − p) + ( 1 − p) E ( X), Subtracting that last term from both sides, we get E ( X) − ( 1 − p) E ( X) = ( 1 − p). The left side of that equation simplifies to p E ( X). Then we have p E ( X) = 1 − p. WebGeometric distribution is a type of discrete probability distribution that represents the probability of the number of successive failures before a success is obtained in a …
