(choose chapter or problem)

Refer to Exercise 4. The total number of assemblies that fail to meet specifications is $X+Y $ .

a. Find $\mu_{X+Y}$.

b. Find $\sigma_{X+Y}$.

c. Find $P(X+Y=3)$

Equation Transcription:

$X\ +\ Y$

${\mu{}}_{X\ +\ Y}$

${\sigma{}}_{X\ +\ Y}$

$P(X\ +\ Y=3)$

Text Transcription:

X + Y

\mu_X + Y

\sigma_X + Y

P(X + Y=3)
