experimental probability of simple events

Question

AFTER THE MOVIE prermiere 99 out of 130 people surveyed said they liked the movie what is the experimental probability the the next person surveyed will say he or she did not like the movie

 

Answer 1

Based on the survey, the fraction of people liking the movie was 99 / 130  = 0.76 = 76%

 

The key assumption is that the same pattern will apply to a larger population.  In other words, the 130 people surveyed are assumed to be representative of the larger population.

 

Based on this, the probabily of the next person liking the movie is 76%
