Answer 2

To calculate the result of the expression, simply multiply all the fractions together:

(2/13) * (3/12) * (1/10) * (1/9) * (1/8) * (1/7) * (1/6) * (1/5) * (1/4) * (1/3) * (1/2) * 1

When you multiply fractions, you can multiply the numerators together and the denominators together. Cancel out any common factors to simplify:

2 * 3 * 1 * 1 * 1 * 1 * 1 * 1 * 1 * 1 * 1 * 1 / (13 * 12 * 10 * 9 * 8 * 7 * 6 * 5 * 4 * 3 * 2 * 1)

Now, simplify the multiplication:

6 / (13 * 12 * 10 * 9 * 8 * 7 * 6 * 5 * 4 * 3 * 2 * 1)

Now, calculate the value of the denominator:

13! = 13 * 12 * 11 * 10 * 9 * 8 * 7 * 6 * 5 * 4 * 3 * 2 * 1

Since we can cancel out the common factors in the numerator and denominator, we get:

6 / 13!

Now, calculate the value of 13!:

13! = 6227020800

Finally, divide 6 by 6227020800:

6 / 6227020800 ≈ 9.66 x 10^-7

So, the result of the expression is approximately 9.66 x 10^-7.
