Please help me solve. I have to answer I just need to know how to get it.

Consider that you and a friend are planning to watch 2 movies. There are 20 movies in their collection and you have chosen your 2 favorites (but have chosen not to say what they are) Your friend decides to choose the movie at random. What is the probability that your 2 movies will be the 2 movies your friend's random process selected?

Step 2Suppose the movies you have chosen has a preferred order as well. (For example, if you choose a movie and its sequel) What is the probability that your movies will be chosen in the correct order?
