The image appears to depict part of a mathematical expression involving combinatorics or probabilities. Here's a breakdown of what can be interpreted:

\[
\binom{N}{N_1} p^{N_1} q^{(N - N_1)}
\]

This is a binomial probability term, which is used to compute the probability of getting exactly \(N_1\) successes in \(N\) independent trials, with \(p\) being the probability of success and \(q = 1 - p\) being the probability of failure.

Here's the meaning of the components:

- \(\binom{N}{N_1}\) is a binomial coefficient, read as "N choose \(N_1\)," and it counts the number of ways to choose \(N_1\) successes from \(N\) trials.
- \(p^{N_1}\) is the probability of having \(N_1\) successes, where each success occurs with probability \(p\).
- \(q^{(N - N_1)}\) is the probability of having \(N - N_1\) failures, where each failure occurs with probability \(q = 1 - p\).

This expression is used in binomial distributions, often represented as:

\[
P(X = N_1) = \binom{N}{N_1} p^{N_1} q^{N - N_1}
\]

Where \(X\) is a random variable following a binomial distribution.
