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?

:question: Some people choose friends who are different from themselves. Others choose friends who are similar to themselves. Compare the advantages of having friends who are different from you with the advantages of having friends who are similar to you. Which kind of friends do you prefer for yourself? Why? :idea: In choosing friends, different people show different preferences. Some people prefer to choose friends who are different from themselves, while the others prefer to choose friends who are similar to themselves. Each of both preferences has its own advantages. From experience, I have learned about those advantages such as follows. Those who choose friends who are different from themselves state that one of the main reasons of making friends is to enrich their lives. They find that making friends with people who are different from themselves helps them enrich their lives. For example, by talking to or having discussions with their friends, they have good opportunities to gain new thoughts, ideas, opinions, etc. which they have never known or thought of before. By participating in activities with their friends, they have good opportunities to learn new lessons, experiences, or skills which they have never tried out or even heard of before. In brief, with friends who are different from themselves, they can share many opportunities from which they can gain many new and useful experiences, views, opinions, etc, and broaden their views and understanding. Those who choose friends who are similar to themselves are usually people who want to keep their lives simple and don’t expect any radical changes. By making friends with people who are similar to themselves, they can keep their lives simple because they don’t have to bother with many new or unfamiliar things which are often found to cause troubles. Subsequently, they can save much time and energy and they don’t have to change the way they are. For example, when their friends invite them to have a talk or have discussions, they can expect that the topics are about anything they are familiar with or fond of, rather than anything strange or weird which is often found to be unacceptable. When they join in their friends’ activities (such as cooking or sports), they can expect enjoyment, since they are familiar with the activities and know how to make the best use of the activities, rather than trying out something completely new which is often found to be confusing or annoying. As for me, I prefer to make friends with people who are different from myself, since I always look forward to new and useful experiences. From experience, I find that making friends with people who are different from me helps me enrich my life because from them, I can learn many new things which I can’t expect from people who are similar to me.

:question: Some people prefer to spend time with one or two close friends. Others choose to spend time with a large number of friends. Compare the advantages of each choice. Which of these two ways of spending time do you prefer? Give reasons to support your answer. :idea: Different people have different preferences in spending their time. Some people prefer to spend time with one or two close friends, while the others choose to spend it with a large number of friends. Each one of them has his/her own reasons which lead him/her to either of both preferences. According to those who prefer to spend time with one or two close friends, spending it with a few close friends enables them to build intimacy and deep relationship. With a few intimate friends, they can share their deepest thoughts and feeling, and enjoy the intimacy while still retaining their privacy. Every time they want to share their thoughts or feeling, they know for certain whom they can confide in. According to those who prefer to spend time with a large number of friends, spending it that way gives them much more merriment than only with a few friends, because they can expect more stories, more jokes, and more laughter to share. Moreover, the presence of many friends often brings out new ideas or new atmosphere which can brighten up the day. A friend of mine tells me that every time he finds himself in a gloomy mood, he will go to the café in which he can expect to meet many friends of his. There, in their company, he often manages to enliven the rest of his day, since his friends never fail to cheer him up with unexpected but pleasant jokes and stories. As for me, I prefer to spend my time with a few close friends. I share the same reasons with those whose preference mentioned above is the same as mine. Besides, I prefer tranquility and quietness in my time. I can’t expect both if I have to spend time with a lot of people.
