A multiple-choice test consists of 9 questions. Each question has answer choices of a,b,c,d, and e, and only one of the choices is correct. If a student randomly guesses on each question, what is the probability that she gets fewer than 2 of them correct? Carry your intermediate computations to at least four decimal places, and round your answer to two decimal places. (If necessary, consult a list of formulas.)
Suppose Z follows the standard normal distribution. Calculate the following probabilities using the ALEKS calculator, Round your responses to at least three decimal places. (a) P(Z≤1.54)= đ (b) P(Z>1.23)= (c) P(−0.39<Z<1.69)=
A rainstorm in Portland, Oregon, has wiped out the electricity in about 10% of the households in the city. A management team in Portland has a big meeting tomorrow, and all 6 members of the team are hard at work in their separate households, preparing their presentations. What is the probability that none of them has lost electricity in his/her household? Assume that their locations are spread out so that loss of electricity is independent among their households. Round your response to at least three decimal places. (If necessary, consult a list of formulas.)
