Answer:
k = 3
Explanation:
K independent file servers
Average "uptime" of each server = 98%
To achieve 99.99% probability by the intranet
given that each server has an uptime = 98%
For the intranet to achieve 99.99% probability we have to choose more than 2 servers ( i.e. 3 servers ) incase any of the server goes down.
As each server posses an uptime of 98% it is almost impossible for all 3 servers to go down at the same time hence value of K = 3
It should be noted that the value of k to achieve 99.99 percent probability will be 3.
From the information given, k is simply the independent file servers.
Also, the average uptime of each server is given as 98%. For the intranet to achieve 99.99% probability, it should be noted that more than 2 servers will be chosen.
In this case, it'll be impossible for the three servers to go down.
