Bad at math and lazy, got quick question.

What is the crit chance with advantage and with disadvantage with 19-20 crit range and 18-20 crit range? :)

According to a spreadsheet I put together a while ago,

Chances of rolling 18 or better:

w/ adv: 27.75%
w/ dis: 2.25%

Chances of rolling 19 or better:

w/ adv: 19.00%
w/ dis: 1.00%

Thank you, appreciate it. :)
