Question: In a CSMA/CD network, three frames fr1, fr2 and fr3 collides. For fr1, it is the first collision; for fr2 it is the second collision;

In a CSMA/CD network, three frames fr1, fr2 and fr3 collides. For fr1, it is the first collision; for fr2 it is the second collision; for fr3 it is the third collision.

a) What is the probability that fr1 suffers from a second collision? Explain your answer. (5 points)

b) What is the probability that fr1 and fr2 are send successfully and fr3 experience collision? Explain (5 points)

c) Suppose now that fr1 was successfully send. However, fr2 collides with fr3. What will happen next? (5 points)

d) What will happen if the two frames continue to collide? (5 points)
