Kendall surveyed the students at her school to find out if they like horror movies and/or animated movies. The table below shows the results of the survey:
Like Horror Movies Do Not Like Horror Movies Total
Like Animated Movies 21 22 43
Do Not Like Animated Movies 56 3 59
Total 77 25 102
If a student likes horror movies, what is the probability that student also likes animated movies? (4 points)
27.2%
48.8%
71.8%
94.9%
48.8%
To find the probability that a student who likes horror movies also likes animated movies, we need to find the number of students who like both horror and animated movies and divide it by the total number of students who like horror movies.
From the table, there are 21 students who like horror and animated movies. So, the probability is:
21/77 = 0.272
Multiplying by 100 to get the percentage, we get 27.2%.
