The answer you seek is 0.75, my friend.
Answer: 0.067
Step-by-step explanation:
Binomial distribution formula :-
, here P(x) is the probability of getting success in x trials , n is total number of trials and p is the probability of getting success in each trial.
Given : n = 4 , p = 12 % = 0.12 and x =2
Then , 

∴ The probability of selecting two nonconforming units in the sample = 0.067
Answer:
This is the right one that's true


X^2 - 10x + 15 = 0
x^2 - 10x = -15
x^2 - 10x + 25 = -15 + 25
(x - 5)^2 = 10 <====
x - 5 = (+-)sqrt 10
x = 5 (+-) sqrt 10
solutions are :
x = 5 + sqrt 10 and x = 5 - sqrt 10
Answer: the square root of -1 is i.
