    Can you show us what you have done, or tell us where you are having
    difficulties and what they are. Then we can direct our efforts to where you
    are having problems.

    I doubt that you will benefit from any of us just doing you assignment for you.

    Surely you must understand at least a few of the problems, or have you just not payed attention in class? After all, I'm not even in high-school and I understand almost half of these problems.

    Hello, kansairacing!

    Surely you can figure out #1 . . .
    If you can't, you might as well forget about tomorrow's exam.
    . . You don't have a chance . . .


    1. An integer from 1 to 50 is chosen at random.

    So . . . obviously . . . there are 50 possible outcomes, right?


    What is the probability that the integer is not divisible by 4?

    How many of the fifty numbers are not divisible by 4?
    Hmmm . . . there's 1 and 2 and 3 . . . and 5 and 6 and 7 . . .

    I have a better idea . . . let's count the numbers that are divisible by 4.
    How many are there?
    Well, every fourth number is divisible by 4: 4,\;8,\;12,\;16,\;\hdots\; 48
    How many is that? . . . twelve!

    So there are: 50 - 12 \:=\:38 numbers that are NOT divisible by 4.

    Therefore: . P(\text{not div by 4}) \;= \;\frac{38}{50}\;=\;\frac{19}{25}



    And we can still use some feedback . . .
    . . Are you learning anything?
    . . Are we doing any good?
    We're doing dozens of homework problems for you
    . . and we don't even get a cookie.

    All you do is give us another dozen problems saying, "I need this ASAP!"
    . . What a surprise! .You're in a hurry . . . the only one.

    I already know your response to this post: "What about the others?"
    . . So don't bother . . .

    All you need to do is to tell us (through a post) if this is helping you understand the problems , or if you're just copying down our answers without looking at the work
