Moe, Larry, and Curly are now inspectors and they look at a critical component of a product.
Their probabilities of detecting a defect are different, namely, 0.99, 0.98, and 0.96, respectively.
If we assume independence,
a. What is the probability that Curly is the only one who detects a defect?
b. What is the probability of at least one of them detecting a defect?
