In a box of 25 external hard disks, there are 2 defectives. an inspector examines 5 of these hard disks. find the probability that there is at least 1 defective hard disk among the 5.

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%.
