Pretend that we just got all the people that liked the movie in a room together. The question is what is the probability that a randomly selected person in that room is aged 18-34 ?

 

probability  =  number of people aged 18-34 in the room / number of people in the room

 

probability  =  num of people aged 18-34 that liked the movie / num of people that liked the movie

 

probability  =  12 / (12 + 5 + 9)

 

probability  =  12 / 26

 

probability  ≈  0.46
