Geometric distribution and Conditional probability problem

I got this problem in my book.. I will directly go the last part which I could not solve.

$P(goodcondition)=0.91854$

$P(badcondition)=0.08146$

a random package check is checked by a company till there is a package in a bad condition .

1. What is the probability that the company will check exactly 4 packages?

2. It is known that the first 3 packages that were checked are in good condition , what is the probability that more than 8 packages will be checked(edit: the answer should be 0.654).
