Question

A factory robot found flaws in 2 out of 12 bulbs. Considering this data, how many flawed bulbs would the robot be expected to find in a batch of 18 bulbs?

Answer 1

so if it’s 2/12 it would be 1 flaw in every 6 light bulbs. so if there were 18 light bulbs there would be 3 flaws (6 * 3 is 18)
