I want to get in Macrob i mean yeah based on probability alone your odds are around 20% but it depends on a few factors, like if you're really smart obviously your odds would be much higher. while 20% do get in its a pretty fallacious statement to make as in the same way i could say that i have a 1 in 100,000 chance to get 5 top 10s (1/10 x 1/10 x 1/10 x 1/10 x 1/10) which is obviously not true
