Which one of the following statements is false? None If X is a poisson random variable the E(X)=(X) =1 If X is a geometric random variable with mean of 1.6 then P(X = 1) is 0.625 Let us consider a sequence of independent Bernoulli trials with p = 0.5. After the sixth sucsess occurs, the expected number of trials to obtained the seventh success is 2.

Question
Which one of the following statements is false?
None
If X is a poisson random variable the E(X) =V(X)=1
If X is a geometric random variable with mean of 1.6 then P(X= 1) is 0.625
Let us consider a sequence of independent Bernoulli trials with p = 0.5. After
O the sixth sucsess occurs, the expected number of trials to obtained the seventh
success is 2.
