A rainstorm in Portland, Oregon, has wiped out the electricity in about 5% 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.)

Binomial distribution because:

Trials are Bernoulli (affected or not)

Probability is known (p=0.05) and remains constant for all trials.

Number of trials is known (n=6).

P(x)=C(n,x)p^x*(1-p)^(n-x)

x=0 =>

P(0)=C(6,0)(0.05^0)(0.95^6)

=0.7351 (approximately)

step-by-step explanation:

$655.61 which is option c

step-by-step explanation:

price of house =   $146,000

initial rate = 3.5%

mortgaged paid in this = 3.5 % of $146,000

                                        =

                                        =$5110

the total years would be = 7

total mortgaged paid = 7 * $5110

                                      =$35770

remaining money = $146000-35770

                                =$110230

new mortgaged payment = 5 % of 110230

                                            =  

                                            =$655.61
