The probability of drawing a face card is 12/52
the probability of drawing an even number is 20/52
face cards and even numbered cards do not overwrap, so no need to subtract anything
Add up: 12/52+20/52=32/52=0.6154

vovangra [49]

Let's call trade balance b, exports e and imports i.

We now construct formula.

b=\Delta{ei}=e-i

Put in the data from last year.

b=968-1658=\boxed{-690}

U.S trade balance for that year is -690 billion dollars.

Answer:

The correct answer is "0.0000039110".

Step-by-step explanation:

The given values are:

Y_n\rightarrow N(\mu, \sigma^2)

\mu = 40n

\sigma^2=100n

n=20

then,

The required probability will be:

= P(Y_{20}>1000)

= P(\frac{Y_{20}-\mu}{\sigma} >\frac{1000-40\times 20}{\sqrt{100\times 20} } )

= P(Z>\frac{1000-800}{44.7214} )

= P(Z>\frac{200}{44.7214} )

= P(Z>4.47)

By using the table, we get

= 0.0000039110
