Question

1. A factory makes light bulbs. Out of 400 light bulbs, 18 were found to have defective filaments.

a. What is the experimental probability that the next light bulb manufactured will have a defective filament?
b. Predict how many bulbs out of 6,000 will have defective filaments.

Answer 1

The answer to A is
`(9)/(200)` because it is
`(18)/(400)` , which can both be halved.
And the answer for B is 270 because 6000 / 14 = 15, so 18 x 15 = 270.

Hope this helps.
