Q. 39 Consider a LAN with four nodes S1, S2, S3 and S4. 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 transmit in the same slot.
The probabilities of generation of a frame in a time slot by S1, S2, S3 and S4 are
0.1, 0.2, 0.3 and 0.4, respectively. The probability of sending a frame in the first
slot without any collision by any of these four stations is______.
Answer: (A)
