Answer:
7/15
Step-by-step explanation:
Determine how much she has watched.
1/3 + 1/5 The common denominator of 3 and 5 is 15. Multiply each fraction by an amount that will make the denominator 15
1/3 = 1*5/(3*5) = 5 / 15
1/5 = 1*3 / (5*3) = 3/15
Now add the two fractions together.
5/15 + 3/15 = 8/15
What is left of the movie? The whole movie = 1 so that which is left is
1 - 8/15
15/15 - 8/15 
7 / 15
She has just a bit under 1/2 to go.
 
        
             
        
        
        
Certain events have a 100% probability of occurring, and impossible events have a 0% chance of occurring.
Theoretical probability is based on a mathematical estimate, whereas experimental probability is a probability determined based off of an experiment.
