[Marvel] What are the odds of a family somewhere sitting alone together and exactly 0 of them getting snapped by Thanos, and how long before they notice half the population is gone?

edit: I never got why people say "wow this blew up" but wow did this blow up

Can't wait to sit down and read all of these great comments. Thanks for the discussion!

Let's say a family is 4 people. You have 50% chance of getting snapped. For all four people in the family to be spared, the odds are 0.5^4 =6.25%

They would probably notice almost immediately as their social media accounts start blowing up.
