Question

A manufacturer tested 7000 LED lights at random and found that 25 of them were defective. If a LED light is selected at random, what is the probability that the selected LED light is a defective one.

Answer 1

25/7000
=1/28
therefore 1/28 is the answer

Answer 2

Answer:

1/280

Step-by-step explanation:

Sample space n(S) = 7000

Let E1 be the event of getting selected LED light is a defective one

n(E1) = 25

p(E1) = n(E1)/n(S)

= 25/7000

= 1/280
