A DELL computer hardware has a yearly 17% rate of failure. Answer the following question. Round the answer up to six decimals; leave them in decimal form.
What is the probability that, if you buy four (4) computers, at least one (1) computer will not fail?!
Probability that all four computers will fail: P 1 = 0.17 x 0.17 x 0.17 x 0.17 = 0.000835 Probability that at least one will not fail : P = 1 - P 1 = 1 - 0.000835 = 0.999165 Answer: C ) 0.999165 = 99.9165 %
