We know that the probability that each calculator is defective is 10%, or 0.1.

probability the first calculator is defective = 0.1
probability the second calculator is defective = 0.1
probability the third calculator is defective = 0.1

To find the probability that the first AND second AND third are defective, we need to multiply them all together.

%280.1%29%2A%280.1%29%2A%280.1%29+=+0.001

To convert a decimal to a percentage, we multiply by 100.

0.001+%2A+100+=+0.1

So, the probability that all three calculators are defective is 0.1%.
