Hi my son had recently this class-assignment;
In a box there are 100 balls, 27 of them are red and the others 73 are white. You have only 10 attempts to take out a red ball, but every time you take out a ball if it is white to put it inside the box again. So in every attempt 100 balls are inside the box. If after 10 attempts all balls were white, you start over.
You have a 27% of probability of success to get a red ball every 10 attempts but if you play this game infinitely, would there be a different success rate for each different attempt (1st, 2sd, 3rd, 4th and so on)or all attempts will have on average the same number of success?
Any thoughts?
Regards
