Binomial Distribution Formula Explanation:

To understand the formula P [X = x] = nCx px qn-x, let's break it down:

Binomial Distribution:
- The formula belongs to the binomial distribution, which is a probability distribution that describes the number of successes in a fixed number of independent Bernoulli trials.

Parameters:
- n represents the total number of trials
- x represents the number of successful outcomes
- p represents the probability of success in a single trial
- q represents the probability of failure in a single trial (q = 1 - p)

Binomial Probability Formula:
- P [X = x] = nCx px qn-x
- nCx represents the number of ways to choose x successes out of n trials
- px represents the probability of x successes
- qn-x represents the probability of n-x failures

Application:
- This formula is used to calculate the probability of getting exactly x successes in n trials, given the probability of success in a single trial.

Therefore, the correct answer is option 'B' - binomial distribution, as the formula provided is specific to calculating probabilities in a binomial distribution scenario.
