A company manufactures CD drives that have a 1.6% chance of experiencing disc-read errors. If a CD drive is tested for 250 read operations, the number of times it may fail is ? .
Answer:
The number of times CD drives may fail are 4 .
Step-by-step explanation:
Formula
\(Percentage = \frac{Part\ values\times 100}{Total\ value}\)
As given
A company manufactures CD drives that have a 1.6% chance of experiencing disc-read errors.
If a CD drive is tested for 250 read operations .
Percentage = 1.6 %
Total value = 250
Put all the values in the formula
\(1.6= \frac{Part\ values\times 100}{250}\)
\(Part\ value= \frac{1.6\times 250}{100}\)
\(Part\ value= \frac{400}{100}\)
Part value = 4
Therefore the number of times CD drives may fail are 4 .
