The quality control team of a company checked 800 digital cameras for defects. The team found that 20 cameras had lens defects, 25 cameras had charging defects, and 6 cameras had both defects. What is the probability that a camera has a lens defect given that it has a charging defect?

6/25

Step-by-step explanation:

Given two events A and B, the conditional probability of event A is the probability that event A occurs given that event B has occurred. It is calculated as

where

is the probability that both A and B occur at the same time

is the probability that B occurs

In this problem, we call:

A = the camera has a lens defect

B = the camera has a charging defect

Here we have:

a = 20 is the number of cameras with lens defects

b = 25 is the number of cameras with charging defects

c = 6 is the number of cameras having both defects

n = 800 is the total number of cameras

So we have:

is the probability that the camera has both lens and charging defect

is the probability that the camera has a charging defect

So the conditional probability is

a line is an defined derm because it

a)contains an infinite number of points b) can be used to create other geometric shapes c)describes something that does not have width or depth d) is a term that does not have a formal definition. a line is an undefined term because it: contains an infinite number of points.
