Use the Poisson model to approximate the probability. Round your answer to four decimal places.
-The rate of defects among CD players of a certain brand is 1.5%. Use the Poisson approximation to the binomial distribution to find the probability that among 430 such CD players received by a store, there are exactly three
Defective CD players.
A) 0.9293
B) 0.0530
C) 0.1414
D) 0.0707
E) 0.1060

The Poisson parameter λ is calculated as 430 * 0.015 = 6.45. The probability of exactly 3 defects is given by (e^(-6.45) * 6.45^3) / 3! = 0.0707.
