7. Find the probability of the battery picked

A manufacturing company stores 1580 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 \(\frac{3}{4}^{th}\) 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.]
