dicelab 0.7-4build1 (arm64 binary) in ubuntu cosmic

 With dicelab you can express most dice rolls (and similar things) in a
 functional language, and then either roll the expression, or evaluate the
 statistical distribution. In the latter case you can choose whether you want to
 simply roll and tally many times, or actually compute the distribution (which
 is more precise, but takes a long time in some obscure cases).
