Right, the reason it won't ever emit F is because RND(1) will never return 1, it's implementation will return 0<=X<1, and INT() is a truncation, so INT(RND(1) + 15) will return an integer between 0 and 14. Adding one gives 1 to 15, and since F is in the 16th position of the string (Apple BASIC indexed from 1, not 0) it will never get selected.

INT(RND(1)+15) will always return 15 and nothing else, since the expected output would be a rounded-down integer value of (a random number between 0 and 0.99999999etc999, plus 15).

INT(RND(1) * 15), in contrast will produce a random whole number from 0 to 14. Hence the popular use of, for example, INT(RND(1) * 6)+1 in any given situation where a random number between 1 and 6 is required.

Correct... my mistake, I put "+" when the original code was "*".
