The answer is exponential
Probability of survival of one disk, p=1-0.05=0.95
If there are n drives, and failures are independent (e.g. mechanical wear and tear, and not a lightning strike or a current spike), then
Probability of survival = p^n
(a) for two disks, P(2) = 0.95^2=0.9025
(b)for three disks P(3) = 0.95^3 = 0.8574
11/2*3/4+1/78=9/8*5/8
5.5*3/4+1/78=9/8*5/8
16.5/4+1/78=9/8*5/8
4.125+1/78=9/8*5/8
4.125+0.013=9/8*5/8
4.125+0.013=1.125*5/8
4.125+0.013=5.625/8
4.125+0.013=0.703
4.138=0.703
the answer is 4.138=0.703
hope this helps
A "solution" is where the graph crosses the
x-axis so while the quadratic has no real solutions, the straight line passing through it does as it intersects the x-axis at x=-2.
Hope this helps! :)
