Neco 2017 Data Processing Question 17
Practice objective / multiple choice question 17 from the 2017 Neco Data Processing examination.
An information system processes data in cycles consisting of three stages: Input (4 min), Process (6 min) and Output (3 min). After each output, the system checks the error level; if the error exceeds 2 % a feedback stage of 5 min is performed before the next input. The probability that the error exceeds the threshold for any given cycle is 0.25, independent of other cycles. If the system processes 8 independent batches, what is the expected total time (in minutes) required to complete all cycles?
