Question

A producer of electronic book readers is performing a quality check to ensure the reader’s backlight is working correctly. The plant manager tests 2,000 readers on Monday and finds that 8 have defective backlights. The fraction 1/x is the experimental probability of a book reader having a defective backlight. What is the value of x?

Answer 1

the value of x is 250

Answer 2

Answer: x=250

Explanation:

Given: Total number of reader’s backlight tested by plant manager=2000

The number of defective backlights=8

Now, the experimental probability of a book reader having a defective backlight is given by :-

`(1)/(x)=(8)/(2000)\\\\\Rightarrow(1)/(x)=(1)/(250)\\\\\Rightarrow x=250`

Hence, the value of x = 250.
