Question

The quality control manager at a battery factory picks three batteries at random each day from the production line.

All of the batteries produced that day will be shipped only if all three batteries chosen are in perfect condition. If in
reality 90% of the batteries produced are perfect, what is the probability that at least one imperfect battery will be
selected?
O 0.001
O 0.081
O 0.243
O 0.271
O 0.729

Answer 1

Answer : 0.001

Step - by - step explanation :

If 90% of the batteries are produced perfectly which equals to . . . 90 / 100. That therefore means that 10 / 100 of the batteries are imperfect.

So it's 0.001 !
