Internet sites often vanish or move so that references to them cannot be followed. In fact, 13 % of Internet sites referenced in major scientific journals are lost within two years after publication. If a paper contains eight Internet references, what is the probability that all eight are still good two years later? Round your answer to three decimal places. What specific assumption must be made in order to calculate the probability? One does not need to make any assumptions; this is just a straightforward calculation. The paper containing the references must be obtained by random sampling. The occurrence of the site references in the paper are independent events. The occurrence of the site references in the paper are disjoint events, P (all eight are still good) =

0.328, the occurance of the site references in the paper are independent,

Step-by-step explanation:

Probability that site is lost: p=0.13

Probability that site is good: q= 1-0.13= 0.87

Probability that all eight sites are good= q^8= 0.87^8= 0.328

Paper is not a variable in this question.

all the eight occurances of the site references in the paper must be independent from each other

the probability of occurance of one site is not mutually exclusive from probability of occurance pf another site

your question is incomplete, write all the numbers in the sequence that it tells you.  

step-by-step explanation:

guess at question:

a vertical line intersects the graph of g(x,y) = 0 at two points. what conclusion follows about the function f(x) implicitly defined by g(x,f(x)) = 0?

the domain of f(x) cannot include the x coordinate of any such vertical line.

informally, f(x) is not a function, and

g(x,y)=0 cannot be solved for y uniquely.

the relation r = {(x,y) such that g(x,y) = 0} is a function if

for all (a,b) ∊ r and (c,d) ∊ r, a=c implies b=d.
