Answer:
12 defective widgets
Step-by-step explanation:
Here we calculate the "experimental probability:" 4 defective widgets out of 94 widgets comes out to a probability of being defective of 4/94, which of course could be reduced.
But we can go ahead and calculate the expected number of defective widgets by mult. that 282 widgets by the probability 4/94:
282 4
------- * ------- = 12
1 94
In this sample of 282 widgets, we could expect that 12 will be defective.
