Answer:
Equation Form : x=-3 y =0
Answer:
the probability that it is not a drama movie is 15/23
Step-by-step explanation:
To calculate the probability we have to make the number of favorable events divided the number of possible events
number of possible events = x
to calculate it we add all the movies
x = 10 + 5 + 8
x = 23
number of favorable events = y
to calculate it we subtract the drama movies from the total of movies
y = x - 8
y = 23 - 8
y = 15
now we divide 15 by 23 and we get the probability
15/23
