A company manufactures cd drives that sometimes experience disc-read errors. if a cd drive is tested for 250 read operations and
fails 4 times, what is the probability that a cd drive will fail? round your answer to the nearest tenth. the probability that a cd drive will fail is %.
The probability that a Cd drive will fail is 1.6 %.
<h3>What is probability?</h3>
Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true. The probability of an event is a number between 0 and 1, where, roughly speaking, 0 indicates impossibility of the event and 1 indicates certainty.
Given,
Cd tested = 250 read operations
Cd fails = 4 times
probability =
here we have,
Probability = 4/250
= 0.016
= 0.016 × 100
= 1.6 %

5/16 = n/80 bring 80 over to the other side to leave n alone. 80 then gets a multiplication sign in front of it. 5/16 x 80=n 5/16=0.3125 0.3125x80=25 n=25 hope this helps
