Answer: 0.6521
Step-by-step explanation:
According to the Binomial distribution , the provability of getting x successes in n trials is given by :-
, where p=probability of getting success in each trial.
Let x denotes the number of defective products.
here , n=7 and p =0.14
Then, the probability that among 7 randomly selected products, at least one of them is defective= P(X ≥ 1) =1- P(X<1)
= 1- P(X=0)
![=1-(1(1)(0.86)^7\ \[\because ^nC_0=1]](https://tex.z-dn.net/?f=%3D1-%281%281%29%280.86%29%5E7%5C%20%5C%5B%5Cbecause%20%5EnC_0%3D1%5D)
Hence, the probability that among 7 randomly selected products, at least one of them is defective is 0.6521 .

Part 1) 
or 1/(n^2) goes in the box.
Part 2) The series <u>converges</u>
======================================================
Work Shown:
Because L is finite and positive, i.e. 
, this means that the original series given and the series
either converge together or diverge together due to the Limit Comparison Test.
But the simpler series is known to converge (p-series test).
Therefore, the original series converges as well.
The two series likely don't converge to the same value, but they both converge nonetheless.
Answer:
4th option
Step-by-step explanation:
noting that i² = - 1
(8i)(5i)(- 4 - 6i)
= 40i²(- 4 - 6i)
= 40(- 1)(- 4 - 6i)
= - 40(- 4 - 6i) ← distribute parenthesis by - 40
= 160 + 240i
What's up? if Elena wants the fraction to equal 1 whole, it would be 7/7. this is because 7 divided by 7 is 1! this can also be thought of as a pie. if there are 7 slices of pie with 7 still remaining, that's 1 whole pie
