I am trying to determine the probability of this scenario:

There is a population size of 955 people. Each one is assigned a random number, 1-955. I am looking at a sample of 26 people from this 955 sample, who have been assigned numbers randomly. I want to know what are the odds of a few things:

1. That all 26 people receive a number lower, meaning closer to 955, then 500

2. That 40% and then 50% of the 26 people receive a number lower, meaning closer to 955, then 500

3. That two people out of this 26 people get consecutive numbers, example: 730 and 731.

Thank you
