A shipment of 50 inexpensive digital​ watches, including 10 that are​ defective, is sent to a department store. The receiving de
ddd [48]

Answer: 0.8926

Step-by-step explanation:

Given : A shipment of 50 inexpensive digital​ watches, including 10 that are​ defective.

The probability that a digital​ watch is defective : p=\dfrac{10}{50}=0.2

Sample size : n=10

Also, they reject the whole shipment if 1 or more in the sample are found defective.

Using the binomial probability formula :

P(x)=^nC_xp^x(1-p)^{n-x}

Let x be the random variable that represents the number of defective watches.

The probability that the shipment will be​ rejected :-

P(x\geq1)=1-P(0)\\\\=1-^{10}C_0(0.2)^0(0.8)^{10}\\\\=1-(0.8)^{10}=0.8926258176\approx0.8926

Hence, the probability that the shipment will be​ rejected = 0.8926

The remainder of the expression x/(x + 1) is a negative one. Then the correct option is D.

<h3>What is division?</h3>

The division means the separation of something into different parts, sharing of something among different people, places, etc.

The expression is given below.

\rm \rightarrow \dfrac{x}{x+1}

Add and subtract 1 in the numerator, then we have

\rm \rightarrow \dfrac{x+1-1}{x+1}\\\rm \rightarrow 1 -\dfrac{1}{x+1}

Then the remainder will be a negative one.
