    Write the number of permutations in a factorial form. Then simplify. How many different ways can you and four of your friends sit in the backseat of a limousine?

    Did they give you any multiple choice answers or not? I'm also researching permutations in a factorial form because i've never had to do them like that

    A bag contains 2 white marbles and 7 purple marbles. Two marbles are drawn at random. One marble is drawn and not replaced. Then a second marble is drawn. a) What is the probability of selecting a purple marble and then a white marble? b) what is the probability of selecting two white marbles? c) Is there a greater chance of selecting two white marbles ina row or two purple marbles in a row?

    Okay so there are 9 marbles in total ( 7 + 2 ) and there are 7/9 purple and 2/9 white. So what's your probability of selecting a purple marble? And then a white marble?

    The chances of the first marble being purple is 7/9 because we have 9 marbles in total and 7 of them are purple. But if we take one purple out of the bag, there is only 6/8 left. 7/9 * 6/8 = 7/12

    For being able to select two white marbles, just change the numbers to be correct for the white marbles ( 2/9 * 1/8 ) = 1/36

    The last question is asking if you think you have a greater chance of picking out two marbles in a row or two purple marbles in a row. The answer is purple because it's 7/12 vs. 1/36 meaning there is more purple ( while there are only 2 white marbles, there are 7 purple marbles )

    the 2/9 turns to 1/8 because you have 2 white marble out of 9 but if you select one white marble, you're left with only one white marble and only 8 marbles in total.
