Answer:
20%
Explanation:
To find the percentage of movies that Lamar rated as very good out of the total movies he watched, we can use the formula:
Percentage = (Number of movies rated as very good / Total number of movies watched) * 100
In this case, Lamar watched 50 movies in total, and out of those, he rated 10 movies as very good.
Using the formula, we can calculate the percentage:
Percentage = (10 / 50) * 100 = 20%
Therefore, Lamar rated 20% of the movies he watched over the whole year as very good.
