Events A and B are mutually exclusive whenA) the suffer probability of the two offsprings is zero. B) they are independent founts. C) P(A)P(B) = 0D) P(A)P(B) = P(A | B)Answer: A2. Independent events A and B would be consistent with which of the avocation statements:A) P(A) = .3, P(B) = .5, P(A B) = .4B) P(A) = .4, P(B) = .5, P(A B) = .2C) P(A) = .5, P(B) = .4, P(A B) = .3D) P(A) = .4, P(B) = .3, P(A B) = .5Answer: B3. The probability of event A occurring given event B has occurred is an example ofA) a marginal probability. B) a conditional probability. C) a joint probability.

If each of two independent adept file servers has a reliability of 93% and e ither merely weed run the weave site, then the overall web site availability isA) 0.9951B) 0.8649C) 0.9300D) 0.9522Answer: AP ( A) = .93 P (B) = .93 P (A ? B ) = .93*.93 = .8649P (A U B ) = P (A) + P (B) - P (A ? B )= .93 + .93 - .8649= .9951Use the following to answer 5 - 95. P(V ) is approximatelyA) .20B) .40C) .50D) .80Answer: DP ( V ) = = .2Hence P ( V?) = 1- P (V)= 1 - .2= .86. P(W S) is approximatelyA) .12B) .30C) .40D) .58Answer: AP ( W ? S ) = = .127. P(A M) is approximatelyA) .25B) .50C) .625D) .125Answer: CP(A M) = P (A) + P ( M) ? P ( A ? M... If you want to get a near essay, fiat it on our website: OrderEssay.net
