Binary signals are transmitted at a constant rate of 1000 per second. Suppose that trans- mission errors occur independently with a probability of p = 0.001. (a) What is the probability that there are 2 or more transmission errors in 2 seconds? (b) What is the probability that the first transmission error occurs in 2 seconds? (c) What is the average number of successive error-free transmissions? (d) What is the probability that the fifth transmission error occurs within 3 seconds? (No need to simplify) (e) What are the mean and standard deviation of the time (in seconds) when the fifth transmission error occurs?
