03/10/2022, 3:53 AMYou have a pool of 1000 people that you want to launch a product. You want to roll it out in increments of 10 users. Today, youâll randomly sample for 10 users to get the product. Tomorrow, youâll roll it to another 10 users, randomly sampled and so on until eventually everyone gets the product. How long on average does a user have to wait to get this product?This question is taken from 44:24 in this video which has the solution. Iâm not understanding why the probability of being selected remains the same each day. Shouldnât the denominator decrease by 10 each day?
