Create a multi value variable

Hi all:

I am trying to create a random variable that can take 5 values from 0 to 4 with the following probability distribution p0 = 0.36 P1 = 0.16 P2 = 0.16 P3 = 0.16 P4 = 0.16

Could you please help me in this.

Please show some effort!!

Show us what you've tried... have a look at the RAND Function and try some of your ideas!

If you get stuck, we'll help!

Thank you Roberto. My problem is that I am not very experinced in MatLab so I didn't know where to start I will try RAND function. Thanks anyway

To get you started here's a hint in the form of another question. In the following code what are all the possible values of the variable 's' and what are their respective probabilities?

 c = [0.21,0.32,0.65,0.87];
 r = rand;
 s = sum(r<c);

[Mahmoud]

Thanks! If I understood it well then the possible values of s are

2.1, 4.96, 20.8, 37.41.

No, you should try running that code repeatedly and see. Maybe it will give you some ideas.
