the answer is 1/500 because it will always be the probability of the event occurring/total events

Answer:

Option A is correct.

Step-by-step explanation:

Given: Number of transistors in a lot = 500

            Number of defective transistors in a lot = 1

To find: Probability of selecting a defective transistor from the lot.

[tex]Probability=\frac{Number\:of\:Favorable\:Outcome}{Total\:Number\:of\:Outcome}[/tex]

[tex]Probability\:of\:getting\:a\:bad\:transistor=\frac{1}{500}[/tex]

Therefore, Option A is correct.
