Probability distributions play a crucial role in statistical analysis by describing the likelihood of different outcomes in a given set of events. There are several probability distributions, each with its own characteristics and use cases. In this context, we'll discuss a few important probability distributions and then solve the provided problem using these concepts.

### Probability Distributions:

1. Binomial Distribution:
   - The binomial distribution is characterized by two parameters: the number of trials (\(n\)) and the probability of success in a single trial (\(p\)).
   - Formula: \(P(X = k) = C(n, k) \cdot p^k \cdot (1-p)^{n-k}\), where \(C(n, k)\) is the binomial coefficient.
