An optical inspection system is used to distinguish among different part types. The probability of a correct classification of a

ny part is 0.96. Suppose that three parts are inspected and that the classifications are independent. Let the random variable X denote the number of parts that are correctly classified. Determine the probability mass function of X. Round your answers to four decimal places (e.g. 98.7654).

Answer:

Probability Mass Function:

   x:          0                         1                            2                          3

P(x):          0.000064          0.004608             0.115902             0.884736

Step-by-step explanation:

We are given the following information:

We treat correct classification  as a success.

P(correct classification) = 0.96

Then the number of classification follows a binomial distribution, where

P(X=x) = \binom{n}{x}.p^x.(1-p)^{n-x}

where n is the total number of observations, x is the number of success, p is the probability of success.

Now, we are given n = 3 and x = 0, 1, 2, 3

We have to evaluate:

P(x = 0)\\= \binom{3}{0}(0.96)^0(1-0.96)^3\\=0.000064

P(x = 1)\\= \binom{3}{1}(0.96)^1(1-0.96)^2\\=0.004608

P(x = 2)\\= \binom{3}{2}(0.96)^2(1-0.96)^1\\=0.115902

P(x = 3)\\= \binom{3}{3}(0.96)^3(1-0.96)^0\\=0.884736

PMF:

   x:          0                         1                            2                          3

P(x):          0.000064          0.004608             0.115902             0.884736

sergey [27]
Take 0.53 and 0.7 by 100 to make them percents. 0.53 times 100 is 53% and 0.7 time 100 is 70%. so 0.7>0.53

Solve the following system of equations.<br> 2x+y=3<br> I= 2y - 1<br> x=<br> y=
marin [14]

<em>Note: I am assuming your second equation is:</em>

<em>x = 2y - 1</em>

<em></em>

Answer:

The solution to the system of equations is:

  • x = 1
  • y = 1

Step-by-step explanation:

Given the system of equations

2x+y=3

x = 2y - 1

solving the system of equations using the elimination method

\begin{bmatrix}2x+y=3\\ x=2y-1\end{bmatrix}

Arrange equation variables for elimination

\begin{bmatrix}2x+y=3\\ x-2y=-1\end{bmatrix}

Multiply x-2y=-1 by2:     2x-4y=-2

\begin{bmatrix}2x+y=3\\ 2x-4y=-2\end{bmatrix}

subtracting the equations

2x-4y=-2

-

\underline{2x+y=3}

-5y=-5

now solve -5y = -5 for y

-5y=-5

Divide both sides by -5

\frac{-5y}{-5}=\frac{-5}{-5}

Simplify

y=1

For 2x+y=3 plug in y=1

2x+1=3

subtract 1 from both sides

2x+1-1=3-1

Simplify

2x=2

Divide both sides by 2

\frac{2x}{2}=\frac{2}{2}

Simplify

x=1

Therefore, the solution to the system of equations is:

  • x = 1
  • y = 1
