Question

A company manufactures 10000 Laptops in 6 months. Out of which 25 of them are found to be defective. When you choose one Laptop from the manufactured, what is the probability that selected Laptop is a good one?

Answer 1

Total number of laptops = 10000

∴ n(S) = 10000

Number of good laptops = 10000 – 25 = 9975

Let E be the event of getting good laptops

n(E) = 9975

P(E) = `("n"("E"))/("n"("S"))`

= `9975/10000`

= `399/400`

= 0.9975
