if there is 176 people in an event and only 10 get chosen,what is the probability that i get chosen

Answer 1

IF you're there and they choose randomly, you have a 10/176 chance = 5/88 chance = about 5.7% chance of being chosen

If you're not one of the 176 and you're not there, you have zero chance of being chosen

If they choose non-randomly, your chances are anywhere from zero to certainty.
