Question

a factory makes car batterys the probability that the battery is defected if every 1/11 batterys are defected and 500 cars batteries are made how many are defected a 45 b 30 c 489 d 11

Answer 1

Step-by-step explanation:

A German manufacturer of luxury cars reveals that of 400 car batteries returned under warranty, 200 are working well and have no problem. Low charge and acid stratification are the most common causes of the apparent failure. The car manufacturer says that the problem is more common on large luxury cars offering power-hungry auxiliary options than on the more basic models.

Answer 2

Answer:

45.45 batteries

Step-by-step explanation:

The probability of any random battery being defective is 1 in 11, the number of expected defects in a population of 500 batteries is given by:

$E = \frac{1}{11} * 500$

E = 45.45 batteries

45.45 batteries are should be defective.
