Consider a sequence of independent Bernoulli trials, where $\frac{3}{4}$ is the probability of success in each trial. Let ‘X’ be a random variable defined as follows: If the first trial is a success, then ‘X’ counts the number of failures before the next success. If the first trial is a failure, then ‘X’ counts the number of successes before the next
failure. Then 2E(X) equals …….
