- Suppose that $X$ is a geometric random variable and draw a tree diagram that illustrates how the benrnoulli trials that compose this random variable pan out for $X=1$, $X=2$ and $X=3$
- Assuming that the probability of sucess in each individual trial is equal to $p$ write out expressions for $P(X=0)$, $P(X=1)$, $P(X=2)$ and $P(X=3)$ if $X$ is a geometric random variable.
