Answer 2

Probability of the Checked Refrigerator Being Defective

To find the probability that the randomly selected refrigerator is defective, we need to consider the total number of refrigerators and the number of defective refrigerators.

Given: - Total number of refrigerators: 3000 - Number of defective refrigerators: 6

To calculate the probability, we divide the number of defective refrigerators by the total number of refrigerators:

Probability of the checked refrigerator being defective = (Number of defective refrigerators) / (Total number of refrigerators)

Substituting the given values:

Probability of the checked refrigerator being defective = 6 / 3000

Simplifying the fraction:

Probability of the checked refrigerator being defective = 1 / 500

Therefore, the probability that the checked refrigerator is defective is 1/500.
