The probability that 4 red cards and 9 black cards are dealt is 0.0735.
Let E be the event that 4 red cards and 9 black cards are dealt.
According to the given question.
Number of card hand that is dealt from a well-shuffled standard 52- card deck is 13
Total number of red cards in a well shuffled card deck = 26
Total number of black cards in a well shuffled card = 26
Now, the number of ways to dealt 13 cards = 
Number of ways to dealt 9 black cards = 
And, the number of ways to dealt 4 red cards = 
As, we know that the probability of an event is calculated by taking the ratio of the favorable outcomes to the total number of outcomes.
Therefore, the the probability that 4 red cards and 9 black cards are dealt is given by
P(E) = 
⇒ P(E) = 
⇒ P(E) = 0.0735
Hence, the probability that 4 red cards and 9 black cards are dealt is 0.0735.

Answer:
(6,20) because both lines pass through this point
Step-by-step explanation:
To solve this you can use the substitution method.
Since both of them are equal to y, substitute one of the equations for y, that way you have x+14 = 3x+2. From here you continue to simplify.
Eliminate x from either side of the equation. For example, subtract x from the side that says "x+14". (Make sure you are also subtracting it from the other side of the equal sign as well.
Once you do this you should now have 14 = 2x+2
In order continue, you now have to get x by itself. So now subtract 2 from both sides of the equation. After doing this, you should have 12 = 2x
You then simplify x by dividing both sides by 2. This will get you x = 6
Now that you have the x-value, substitute that into either of the two equations (it is recommended you substitute it into both equations to make sure you have the correct x-value). For example: If I substitute x into Line C's equation, I will now have y = 6 + 14.
6 + 14 is 20, therefore you're y-value is y = 20

What is supposed to be the underlined digit
Answer:
417 is the number of adults that would erase their personal information online if they could, they are the 61%. The complete number is 417,85, but we have to adjust the answer for people.
Step-by-step explanation:
To find the answer we need to do a Rule of Three. The Rule of Three is a Mathematical Rule that will help us to solve problems based on proportions.
1. I know that a 685 adults were surveyed, so this is the 100%. 61% say they would erase all of their personal information online if they could, and we don't know the numbre of people in here.
2. So 685 adults _____ 100%
X adults _____ 61%
Here we have to put the same elements in the same columns. Students with studients and percentage with percentage.
3. Now I have to cross these details. I have to multiple 61*685. So:
61*685= 41785
4. Then divide that result by 100.
41785/100= 417,85
5. So 417 is the total number of adults that would .
