An inspector samples four PC’s from a steady stream of computers that is known to be 12% nonconforming. What is the probability

yarga [219]

Answer: 0.067

Step-by-step explanation:

Binomial distribution formula :-

$P(X)=^nC_xp^x(1-p)^{n-x}$ , 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 , $P(2)=^4C_2(0.12)^2(1-0.12)^{4-2}$

$\Rightarrow\ P(2)=\dfrac{4!}{2!2!}(0.12)^2(0.88)^2=0.06690816\approx0.067$

∴ The probability of selecting two nonconforming units in the sample = 0.067

7x - y = - 1 (7x + 3y = - 25)

Otrada [13]

Answer:

x = -1

y = -6

Step-by-step explanation:

7x - y = -1 -> y = 1 + 7x

7x + 3y = - 25

Put y = 1 +7x -> 7x + 3(1 +7x) = -25

-> x = -1

-> y = -6
