In a factory 400 discs were checked, out of which 40 were found to be defective. How many defective discs can be found in a sample of 1200 disks?
a.
90
b.
110
c.
130
d.
120


Solution:

Number of disks checked = 400.

Number of disks found defective = 40.

So, the probability of getting a defective disk = 40 / 400
[Number of favourable eventsTotal number of possible outcomes.]

= 1 / 10
[Simplify.]

Number of disks to be checked = 1200.

So, the number of disks which can be found to be defective in a sample of 1200 disks = 1200 × 1 / 10
[Simplify.]

= 120
