Mathematics · Probability and Reliability
In a CBS network, a branch is connected to the central switch via a primary fiber link and a secondary backup satellite link. The probability of the primary link failing in a year is 5% (0.05). The probability of the backup link failing is 10% (0.10). The central switch itself has a failure probability of 0.1% (0.001). Assuming these are independent events, calculate the total probability (in percentage) that the branch will lose ALL connectivity to the central system during the year.
