Today's Nostr clients tend to come with relays preselected but for best resiliency and censorship resistance shouldn't they be more random?

In that case, having at least one shared relay would be necessary for comms between two random users.

If there are 300 relays in operation, how many randomly selected relays should each client connect to for there to be at least one relay overlapping?

This is similar to the birthday problem but I'm not sure how to enter it into any online calculator.
