Let $$\left\{X_i, i \geq 1\right\}$$ be independent and identically distributed random variables with  $$P(X_i = 1) = p = 1 - P(X_i = 0), S_n = \sum_{i=1}^n X_i$$. The distribution of $$S_n$$ is:

A

Geometric distribution with parameter p

B

Bernoulli distribution with parameter p

C

Binomial distribution with parameter n and p

D

Bernoulli distribution with parameter np
