Step-by-step explanation:
(3, -3/2)
The components operate independently, so the probability of "total" system failure is the same as the product of each probability of component failure. That is, if 
denotes the event that component 
fails, then
The are independent and identically distributed, so 
for all 
. So
The

or
Step-by-step explanation:
<u><em>Verify the solution of each case</em></u>
case 1) we have
Divide the compound inequality into two inequalities
---> solution is the interval (-∞,4]
---> solution is the interval [-4,∞)
The solution of the compound inequality is
[-4,∞) ∩ (-∞,4] ----> [-4,4]
case 2) we have
Divide the compound inequality into two inequalities
---> solution is the interval (-∞,-1]
---> solution is the interval [-2,∞)
The solution of the compound inequality is
[-2,∞) ∩ (-∞,-1] ----> [-2,-1]
case 3) we have
---> solution is the interval (-∞,-1]
or
---> solution is the interval [0,∞)
The solution of the compound inequality is ----> (-∞,-1] ∪ [0,∞)
case 4) we have
---> solution is the interval (-∞,3]
or
---> solution is the interval [-1,∞)
The solution of the compound inequality is
(-∞,3] ∪ [-1,∞) ---->(-∞,∞)
