A ping test determines whether a client (computer, smartphone, or similar device) communicates with another device across a network. Assume that the probability of response to a test is 3/4. The test involves a large number of runs and it continues until the first response is recorded. Define the random variable X as the number of runs of the test required to terminate the experiment. Suppose that the condition of one run does not affect that of another.

a. Determine the probability distribution of X.

b. Let A be defined as the event that the experiment ends after an even number of repetitions. Evaluate P(A).

Number of ways to stack $N$ cubes.

Once you get a particular stack of $4$ cubes let's say, the order of the cubes doesn't matter, just which sides are being shown does.

I'm generally finding $2$ numbers:

1) $6\ast {24}^{n-1}$

and

2) $3\ast {24}^{n-1}$

Which is the correct answer, and why?
