The A. B. Company buys calculators from a Korean supplier. The probability of a defective calculator is 10%.
If three calculators are selected at random, what is the probability that at least one of the calculators will be defective?

P(at least one) = 1 - P(none are defective)
= 1 - 0.9^3
= 1 - 0.729
= 0.271
