Without apology, I post... Flowers!

For no other reason than because I want to, I hereby present all the flowers Kouryou-chan spotted and identified on our hike over North Sunrise Ridge, around Frozen Lake, across the Berkeley blast field and down into Berkeley Meadows, July 16th. These are all alpine and subalpine breeds growing on Mount Rainier. All identifications were hers, so if they're wrong, well, we did our best.

Camping, Day 4

Just to warn you, there are a lot of photographs in this pack (24 in total, many of them wide-angle or stitch panos), but so many of them were gorgeous I couldn't bear not to post them.)

I have forgotten my probability theory...

Oh, might LJ Brain, help me with this mathematics problem: a man is a demolition derbyist. The probability of him suffering an injury during any one derby is 0.12.

I know that the probability of him suffering an injury in two derbies is ((0.12 + 0.12) - (0.12 * 0.12)). What's the (generalized) formula for him suffering an injury over n derbies?
