Answer:
0.3667 or 36.67%
Step-by-step explanation:
The probability of getting at least 1 defective hard disk among the 5 (P(X>0)) is equal to 100% minus the probability of getting none defectives (1-P(X=0)).
If 23 out of 25 hard disks are non-defective, the probability is:

The probability that there is at least 1 defective hard disk is 0.3667 or 36.67%.
Answer:
(0,-1)
Step-by-step explanation:
b= 63 and that is your answer
It's C, Y = 2x + 3. This is cause, if we use the table and say that y = 5 and x = 1, then 5 = 1 x 2 + 3 which is correct
