Sample question: If your probability of success is 0.2, what is the probability you meet an independent voter on your third try?
Inserting 0.2 as p and with X = 3, the probability density function becomes:
f(x) = (1 − p)x − 1*p
P(X=3) = (1 − 0.2)3 − 1(0.2)
P(X=3) = (0.8)2*0.2 = 0.128.
Theoretically, there are an infinite number of geometric distributions. The value of any specific distribution depends on the value of the probability p.
