If you ask “what is the chance I roll a 6 on this one die roll?” That never changes at 16.7%.

But if you were to ask ‘what if I roll twice and get at least one 6?” That’s 30%

Chance on 3 rolls? 42%

6 rolls? 67%

But if you rolled 5 times and didn’t get a 6 yet, the chance your last roll is a 6 remains 16.7%.
