Four bits are transmitted over a digital communications
Chapter 2, Problem 23E(choose chapter or problem)
Go Tutorial Four bits are transmitted over a digital communications channel. Each bit is either distorted or received without distortion. Let \(Ai\) denote the event that the \(i\)th bit is distorted, \(i\) = 1, …,4.
(a) Describe the sample space for this experiment.
(b) Are the \(Ai\)'s mutually exclusive? Describe the outcomes in each of the following events:
(c) \(A_{1}\)
(d) \(A_{1}{ }^{\prime}\)
(e) \(A_{1} \cap A_{2} \cap A_{3} \cap A_{4}\)
(f) \(\left(A_{1} \cap A_{2}\right) \cup\left(A_{3} \cap A_{4}\right)\)

ANSWER:
Solution:
Step 1 of 7:
Here it is given that four bits are transmitted over a digital communication channel.
Also, it is given that each bit is either distorted or received without distorted.
Event denotes that bit is distorted,i=1,2,3,4.
Using this we need to find the required values.
