Test is very, very soon, and I don't understand a thing, and unfortunately, I have a teacher is very unwilling to help. All I have is the answers to the following questions, but I have no idea how to get these answers.
1.) Given a bag of M&M's that contains the following colors of candies: 3 blue, 2 red, 6 yellow, 5 green, and 7 brown. How many ways can you chose 3 green, 1 yellow, and 2 blue?
Answer: 180
2.) You get the following identical marbles: 6 yellow, 4 purple, and 5 pink. How many different arrangements can you make of these in a straight line?
Answer: 630,630
3.) Using a standard deck of cards, if four cards are selected at random, find the probability of selecting three face cards and one ace.
Answer: 176/54,145
4.) You are drawing marbles from a container of 7 red marbles, 4 blue marbles, and 4 yellow marbles. What are the odds that you draw two blue marbles?
Answer: 2 to 33
Now, these are the answers my teacher gave us. If you get a different answer let me know. However! What I'm really looking for is how to do all of these problems. Even if you could tell me how to do just one of them, that would be great!
Also, if you know of any websites I could go to that would teach me about how to do problems like these as well as other problems with combinations, permuatations, probability, odds, and binomial probability, that would be great, too!
