7. Find the probability of the battery picked

A manufacturing company stores 1212 batteries in its godown. The batteries were unchecked for more than \(6\) months due to a mandatory lockdown imposed on the city.

 

After the lockdown was released, the staff member finds half of the batteries spoiled.

 

1. If one of the batteries is picked at random, what is the probability that the battery picked is spoiled?

 

The probability of picking a defective battery is $\frac{i}{i}$.

 

 

2. Also, what is the probability of picking a good quality battery?

 

The probability of picking a good battery is $\frac{i}{i}$.

 

[Note: Do not reduce the fraction obtained.]
