Question

Consider a series of independent Bernoulli(p) trials (think, for example, of flipping coins, one after the other). Let alpha be an integer. Let W be a random variable that measures the time of the alpha-th success (in the coin flipping example, think of how many flips have passed until the 10th success - in this example, alpha = 10). What is the probability mass function of W? Namely, for an integer k, what is Pr[W = k]?

          Consider a series of independent Bernoulli(p) trials (think, for example, of flipping coins, one after the other).

Let alpha be an integer.

Let W be a random variable that measures the time of the alpha-th success (in the coin flipping example, think of how many flips have passed until the 10th success - in this example, alpha = 10).

What is the probability mass function of W?

Namely, for an integer k, what is Pr[W = k]?
