A light bulb manufacturer found that 3 out of every 268 light bulbs in every batch were bad. If they produced 22,158 light bulbs, how many are bad?
First, we need to calculate the probability of a light bulb being bad in a batch:
3 bad light bulbs / 268 total light bulbs = 0.011194
This means that approximately 1.12% of light bulbs in a batch are bad.
Next, we need to calculate how many bad light bulbs there would be in a batch of 22,158 light bulbs:
0.011194 * 22,158 = 248.13
Therefore, there would be approximately 248 bad light bulbs in a batch of 22,158 light bulbs.
