Question regarding Trickster 3.2 "Harness the Void"

The 3.2 patch notes just were released and I have a question regarding 3.2 Shadow - Trickster ascendancy "Harness the Void".

Harness the Void: Grants your hits a:
25% chance to gain 25% of Non-Chaos Damage as Extra Chaos Damage,
15% chance to gain 50% of Non-Chaos Damage as Extra Chaos Damage and
5% chance to gain 100% of Non-Chaos Damage as Extra Chaos Damage.

Are these independent chances or can they overlap? Meaning a single hit has a possibility (albeit small) to get all 3 gains (25% + 50% + 100%)
