Final answer:
The probability that the film Molly chooses at random is not an action film is 6/13. This is calculated by subtracting the number of action films from the total films and then dividing by the total number of films.
Step-by-step explanation:
Molly owns 13 films, of which 7 are action films. The question asks us to find the probability that the film she chooses at random is not an action film. To calculate this, we subtract the number of action films from the total number of films Molly owns, which gives us the number of non-action films. Then, we divide this by the total number of films to get the probability.
Number of non-action films = Total films - Action films = 13 - 7 = 6
Probability of choosing a non-action film = Number of non-action films / Total films = 6/13
The fraction 6/13 is already in its simplest form, so the probability that Molly chooses a non-action film is 6/13.
