A single card is drawn from a standard 52-card deck. Let D be the event that the card drawn is a black card, and let F be the

Svetllana [295]

Answer:

$\dfrac{25}{26}$

Step-by-step explanation:

Let

D be the event that the card drawn is a black card
F be the event that the card drawn is a 10 card
F' be the event that the card drawn is not a 10 card

The probability

$Pr(D\cup F')=Pr(D)+Pr(F')-Pr(D\cap F')\\$

Note that

$Pr(D)=\dfrac{26}{52}=\dfrac{1}{2}\\ \\Pr(F)=\dfrac{4}{52}=\dfrac{1}{13}\\ \\Pr(F')=1-\dfrac{1}{13}=\dfrac{12}{13}\\ \\Pr(D\cap F')=\dfrac{24}{52}=\dfrac{6}{13}$

So,

$Pr(D\cup F')=\dfrac{1}{2}+\dfrac{12}{13}-\dfrac{6}{13}=\dfrac{25}{26}$

Zanzabum

Answer:

m = 2

Step-by-step explanation:

W=10+2t has the form y = mx + b, the slope-intercept form. Comparing

y = b + mx to

w = 10 + 2t

we see that the slope, m, is 2. This signifies that the baby gains 2 pounds per month shortly after birth.

There are two (2) whole and two tenths (2/10).

You have to multiply the 2 whole by the denominator and add it to the numerator.

Step by step:

1) 2 and 2/10

2) (2*10) = 20

3) add 20 to 2, then put it on the /10

4) 22/10, then reduce the fraction
