Huge good news! They saw a "fisher" in a park in Cleveland Ohio! This beautiful animal, once spread throughout North America, were extirpated in Ohio by the mid-1800s, due to hunting and habitat loss. But they may be coming back! This is the is the first sighting of a fisher in Cuyahoga County since the 1800s. "The return of fishers and other extirpated species like otters, bobcats and trumpeter swans are a result of conservation efforts and emphasize the importance of our healthy forests, wetlands, waterways and natural areas in Cleveland Metroparks," the park system writes. The fisher is in the same family as weasels, ferrets, martens, badgers and wolverines: the 'mustelids', a fierce group who punch above their weight. They like to eat snowshoe hares, and they're one of the few predators of porcupines - but they also eat anything else that comes their way, including fruits and mushrooms. Despite the name, they rarely eat fish; in fact the name comes from the colonial Dutch word 'fisse'. Although they're agile climbers, they spend most of their time on the forest floor. The newly found fisher was briefly spotted by a trail camera, and you can see it on Instagram here: For more on fishers: image
I solved this without any cleverness, but met an old friend I hadn't seen for a long time. (A number, that is.)
I solved this without any clever tricks. I used to know both the relevant numbers by heart, and they were still lurking in my mind, but one of them is not a number I use very often!
The chances are 1/2ยนโฐ and 1/6โด, respectively. I know 2ยนโฐ = 1024, but what's 6โด? I have a vague memory that it's 1296, but let me think. It's 36 squared. I guess just multiply it out in my mind. 6 times 6 is 36, 6 times 30 is 180, 30 times 30 is 900, 900 + 180 + 180 + 36 = 1080 + 180 + 36 = 1260 + 36 = 1296. Okay, good. So it's more likely to roll 10 heads than to roll four 6's. I'm worrying about 6ยณ and worked out that it's 216. Sounds very familiar. I used to know these numbers better!
