Answer: 27.2%

Explanation:

Formula for probability :


\text{Probability}=\frac{\text{Favorable outcomes}}{\text{Total outcomes}}

To find : If a student likes horror movies, what is the probability that student also likes animated movies.

  • The total number student likes horror movies. (Total outcomes)
  • The number of student likes horror movies and animated movies. (favorable outcomes)

From the given table,

Total outcomes: Number student likes horror movies= 77

Favorable outcomes : Number student likes horror movies and animated movies = 21

Then , the required probability will be :-


\text{P(Animated }|\text{Horror})=(21)/(77)=0.272727\approx27.2\%

Hence, the probability that student also likes animated movies=27.2%
