I did it and got it right.
Hope this helps:)
5/36 (I won't repeat it 3 times :-) )
We just have to calculate the ratio of times an action movie played in the las year, that should be a good indication of the chances for an action movie to be played next, since the reference data is quite large. We're talking about a full year, no just a week or a month.
So, 15 action movies out of 108 movies...
The probability that next movie is an action movie is: 15 / 108 , or 5/36
That's roughly 1/7.
A reasonable estimate of the probability is equal to or
we know that
The probability of an event is the ratio of the size of the event space to the size of the sample space.
The size of the sample space is the total number of possible outcomes
The event space is the number of outcomes in the event you are interested in.
x------> size of the event space
y-----> size of the sample space
In this problem we have
Convert to percentage
It is given that,
Last year the total number of movies = 108
Number of action movies = 15
Based on this data, we need to find a reasonable estimate of the probability that the next movie is an action movie.
So, the required probability is:
Hence, the correct option is B.
this is correct answer please give me brainliest
