4 out of every 25 light bulbs are defective how many light bulbs would you expect to be defective out of 350 light bulbs

Respuesta :

Answer:

Step-by-step explanation:

Given that 4 out of 25 light bulbs are defective .

This can be expressed as a fraction 4/25 .

So, to find the expected number of defective light bulbs out of 350, you can set up a proportion: 4/25 = x/350

x=4x350

       25

x=1400/25

x=56

So, you would expect around 56 light bulbs to be defective out of 350.
