The mean of a binomial distribution is 10 and its standard deviation is 2, write the value of `q` .

Explanation

To solve the problem, we need to find the value of \( q \) in a binomial distribution where the mean is given as 10 and the standard deviation is 2.

### Step-by-step Solution:

1. **Understand the Mean and Standard Deviation of a Binomial Distribution**:
- The mean \( \mu \) of a binomial distribution is given by the formula:
\[
\mu = N \cdot P
