Question

Johnny's inspecting the finished toys in toy factory he found that 4 the toys were damaged and 16 were not based on this data how many of the next 20 toys would you expect to be damaged. Please explain I do not understand

Answer 1

4 is expected to be damaged out of the next 20

Explanation:

From the observation made, we have that 4 of the toys were damaged and 16 were not damaged

Thus, the probability of having a damaged toy is 4/20 = 1/5

Now, for the next 20; we have 1/5 of them expected to be damaged

So, the expected damaged number out of the next 20 will be:

1/5 * 20 = 4
