    About the question 5(a), how should I get the probability of the number that has three different digits? Can I used the answer I obtained from question 4(a), if I use that, then how should I explain or interpret it? Or it have any other way to do it? Or I should get some random number and substitute into that function and get that probability( but this should goes for the answer answer in 5(b)? ) I need some lead about this, and I'm not sure how to get the answer in the question 4(a), I simply get the average value for question 2 and question 3 to revise the subjective probability.
    Any help would be greatly appreciated. Thank you.

    @alexander9408, I have different suggestion. Why don't you take the time to type out the questions?
    The attachment you posted is really hard to read. It's all messy and notated.
    I will not try to read it. If you would type out your exact questions you are more likely to get real help.

    Okay, this question: If a number is generated using the function 1000*\sqrt[5]{n} , where n is the random number between 0 and 1, suggest a value for the probability that the 3-digit integer part (000 to 999 inclusive) of this number has three different digits.
    Any idea about how to do this? Please explain it to me, thank you.
