Hi! I need help with this:
A factory makes light bulbs. The probability that a bulb is defective is 1/12. Of 600 light bulbs are tested, about how many are expected to be defective?

If you can help then thanks <3

Sagot :

Answer:  50

==========================================================

Explanation:

We simply multiply the two values given to us

600*(1/12) = 600/12 = 50

We expect about 50 bulbs to be defective.

Note how if we had 50 bad bulbs, then 50/600 = (1*50)/(12*50) = 1/12 of the batch of 600 bulbs is defective.
