The probability that both are defective when a customer selects 2 cartridges at random from the shelf will be 0.00766.
<h3>What is probability?</h3>
The area of mathematics known as probability studies potential outcomes of events as well as their relative probabilities and distributions. Simply put, probability is the likelihood that something will occur. When we don't know how an event will turn out, we can discuss the likelihood or likelihood of various outcomes. Statistics is the study of events that follow a probability distribution.
Here,
The probability of choosing defective cartridge=7/80
So, the probability of choosing 2 defective cartridge=(7/80)²
=0.00765625
=0.00766
When a customer randomly chooses two cartridges from the shelf, the likelihood that both are flawed is 0.00766.

First, you have to compare same unit of measurement for uniformity. Convert feet to inches, knowing that 1 foot is equal to 12 inches.
3*12 = 36 inches
Each square brick is 3 inches wide. Divide the whole width of the path by the width of each brick to obtain the number of bricks:
36/3 = 12
Thus, there are 12 bricks in the path.
