Okay, so to work this problem out, you need to know how to do probabilities.
first, calculate how many total movies there are. There are:
8 comedy movies
+5 science fiction movies
+7 adventure movies
= 20 movies total
To find out the probability of NOT watching a comedy movie, you should take the total movies minus the number of comedy movies. Doing this will give you the proportion of movies that are <em>not</em> a comedy movie.
total movies - comedy movies = probability of not watching a comedy
20 total - 8 comedy = 12 not comedy
So, you know there are 12 movies that are not comedies out of the 20 total movies. You should write this as a proportion: 12/20. Now, simplify:
3/5 probability that it will not be a comedy.
3/5 can also be written as 0.60 and 60%
<u>So, your final answer is written as any of these:</u>
0.60, 3/5, and 60%
