1. The problem is to evaluate the expression $1 - \binom{6}{1} \times 2$.
2. Recall the binomial coefficient formula: $\binom{n}{k} = \frac{n!}{k!(n-k)!}$, which counts the number of ways to choose $k$ elements from $n$ elements.
3. Calculate $\binom{6}{1}$:
$$\binom{6}{1} = \frac{6!}{1! \times 5!} = \frac{6 \times 5!}{1 \times 5!} = 6$$
4. Substitute back into the expression:
$$1 - 6 \times 2$$
5. Multiply:
$$6 \times 2 = 12$$
6. Finally, subtract:
$$1 - 12 = -11$$
7. Therefore, the value of the expression is $-11$.
