EXPLANATION;
We are given the total number of personal video players as 400. Then we are told that upon inspection, it was discovered that 398 has no defects.
First, we need to take note that an experimental probability is a situation whereby we conduct an experiment and use the results to determine the probability of an event occurring.
For the question provided, the total number of outcomes represents the total number of personal video players. The number that has no defects represents the number of required outcomes in this experiment.
The probability of an event E, is given as;
Therefore, to calculate the experimental probability of this event;
To percentage, we now have, 0.995 times 100;
ANSWER:
The correct answer is option A
