Errors caused by contamination on optical disks occur at a rate of one error eve

Question

Errors caused by contamination on optical disks occur at a rate of one error every 138000 bits. Assume the errors follow a Poisson distribution. What is the mean number of bits until five errors occur? What is the standard deviation of the number of bits until five errors occur? (Round your answer to the nearest integer.) The error-correcting code might be ineffective if there are three or more errors within 105 bits. What is the probability of this event? (Round your answer to 4 decimal places.)

Explanation / Answer

a)

mean = 1 / 138000 * 5 = 0.000036

b)

SD will be the same as the mean because the standard deivation and mean in the poisson distribution is the same

c)
