  1. Raise both sides by e:                    e^{\displaystyle ln(x^2)} = e^{-2}
  2. Simplify equation:                           x^2 = e^{-2}
  3. Square root both sides:                 x = \pm e^{-1}

tigry1 [53]
<h3>Answer:  0.432</h3>

======================================================

Explanation:

There are 8+11 = 19 movies that are either horror or mystery.

This is out of 9+12+8+11+4 = 44 movies total.

Divide the two sums to get 19/44 = 0.43181818181818 approximately.

This rounds to 0.432

There's roughly a 43.2% chance of picking a horror or mystery movie.
