Procedure Random Number Logic

You can multiply random number by 3 to get numbers in the range from 0 to 3.

Try to print the value so you can actually see it.

If you take the code approach, it is System.out.println(STUFF_TO_PRINT);  (you will most likely want to save the generated value to a local variable and then use it to both print and the stuff you want), if you chose to use the procedure system, well , only I can tell you is that there deffinitely is some sort of print to console procedure block , but as I have not used the event/procedure system for like 3 years , I can not tell anything more exact now.

You can use the print block in the Text category of the procedure system.

If you used equal condition instead of the others, then yes - that is the reason, as I am like 98% sure that MCreator uses Math.random() for generating a random decimal in range 0 - 1 (both inclusive) , or if not this one , then either Random#nextFloat() or Random#nextDouble() (which both again generate decimal in the same range).
That is actually why multiplying the result by your desired maximal value gives you all the numbers between 0 and the value.
Example (the maximal value = 10)

• 0.0*10 = 0
• 1.0*10 = 10
• 0.625*10 = 6.25
• 0.97*10 = 9.7
• etc...

Now, how can you solve this? First this sentence 

I could use "<" or ">" signs to specify a range, but that would not work for three or more different outcomes.

is totally wrong. The simplest (but not the only) way to use these is checking in reverse order, so for a scenario, with maximal value 3:

• is X >= 2 --- do stuff , else continue to next check
• is X >= 1 --- do stuff, else do some another stuff (or you can use another check X >= 0)

If you want to use the rounding approach, well you can, even though I think that it is the worst one in terms of performance. You have several options here, each one of them is a bit different:

• Math.round() - round in a way you would expect - so less than 0.5 down, 0.5 or greater up
• Math.floor() - always rounds down (hence the name then name "floor")
• Math.ceil() - always rounds up (hence the name name "ceil")
• int typecast (basically you add (int) before the value so you cast it to int) - same as Math.floor()

In case that you do not want to use the greater than or equal check approach and that you do not want (hopefully) to use the round approach, you can just generate the number as an int from start (and therefore as a non-decimal number) , by using Random#nextInt(). This function has an optional parameter of type int. Without the paramter the method returns a value of a whole number in range 0-1 (so 0 or 1) , if you pass some argument , it generates a number in a range 0 - X (exclusive) , so if I pas a number 4 , it will return a whole number in range 0-3.

I get 0-3 is there a way I can make it 1-3? getting 0 from my Blue Berry Bush doesn't make sense so help would be awesome.

If you add 1 to the random number it would never output 0
