You want to utilize the random block and create a NUMBER local variable (Right side)
I called mine random
Then SET the variable to Random 0,1 * 100
The Set block can be found in Custom Variables tab. The number is found in the math tab so is the multiplication sign
Drag a if, do into the area from the logic and loops tab
Next go to logic operators and take out the second one, with the symbols of comparison. Get the GET block from the custom variables tab. Set the symbol to less than and put your variable on the left side. The right side should be the percentage you want it to fall in.
In the "DO" part put in execute command (then put in the effect command)
