What is 1% 99 people left-handed?
This is a classic riddle: 50 left-handed people must leave a room of 100 (99 lefties, 1 righty) for the percentage of left-handers to drop from 99% to 98%; if just one left-hander leaves, the percentage becomes ~98.99%, not 98%. The key is that removing a left-hander changes the total number, so you need to reach a point where the 1 right-hander becomes 2% of the new, smaller total (49 lefties + 1 righty = 50 people total, 49/50 = 98%).What is the 1% Club 99 left-handed people?
If you had 98 left-handers out of a room of 100 people, then that would be 98%. But when 1 left-handed person leaves the room, the total number of people also decreases by 1 to 99. So the calculation is 98 left-handed people out of 99 total people, which is 98/99 = 98.989898… % and that is still nearly 99%.What if in a room of 100 people 99 are left-handed?
