Question
i need the answer quickly
Consider a LAN with 3 nodes N1, N2 and N3.
Time is divided into fixed-size slots, and a
node can begin its transmission only at the
beginning of a slot. A collision is said to have
occurred if more than one node transmits in
the same slot. The probabilities of
generation of a frame in a time slot by N1,
N2 and N3 are 0.2, 0.4, and 0.6, respectively.
The probability of sending a frame in the first
slot without any collision by any of these
three stations is 1000 What is the value of
X
X?
