# Math Help - Subjective probability

1. ## Subjective probability

I have some problem with question 5(a) and 4(a), any lead for it? Thank you.
(Just in case, this is the first time I used attachment, if you can't see the question, please tell me.)

Might want to indicate which part of the problems you are having an issue with.

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.
