Brennna can go to one movie on her week long spring break. Her choice of movies includes a comedy drama horror or fantasy movie. How many possible outcomes (combinations) can be made?



Answer :

Answer:

4

Step-by-step explanation:

First, we must understand the variables.

She can watch ONE movie.

She has 4 genres of movies.

C (n,k)

C(4,1)

n!/k!(n-k)!

4!/1!(3!)

4!= 24

1!=1

3!= 6

24/1(6)

24/6

24 divided by 6 is 4.

So she gets ONE movie, she can watch one of these 4. The wording could be tricky but it's really just asking how many options can she choose from to watch only ONE.

n= "event" (one movie)

K= "time" (4 at a given choice)
