An Open Probability Question

A random probability question I was pondering mid a stagnant lecture today. I’ll be considering it later, but don’t have the chops to deal with it right now.

Algorithm
input whole number t representing a number of iterations

Draw a node at (0,0)
i=0

While i<t:

For all nodes:

Choose an angle at random
Draw an edge of length 1-(te) where e is an arbitrarily small value
Draw a node at that location
[end for]

i=i+1
[end while]

[end algorithm]

Question 01: Given a whole number t, what is the probability that no two drawn edges intersect and that no two nodes overlap? What is the expected number of such co-incisions?

Modified Algorithm
input whole number t representing a number of iterations

Draw a node at (0,0)
i=0

While i<t:

For all leaves:

Choose an angle at random
Draw an edge of length 1-(te) where e is an arbitrarily small value
Draw a node at that location

Choose an angle at random
Draw an edge of length 1-(te) where e is an arbitrarily small value
Draw a node at that location

[end for]

i=i+1

[end while]

[end algorithm]

Question 02: Repeat Question 01 with the new algorithm.
