Answer: The required probability is 
Step-by-step explanation: Given that an urn contains 6 red marbles and 4 black marbles. Two marbles are randomly drawn one by one from the urn without replacement.
We are to find the probability that both drawn marbles are black.
Let E and F denote the events of two marbles one by one without replacement and let S and S' denote the corresponding sample spaces.
Then, we have
Therefore, the probability that both marbles are red is given by
Thus, the required probability is
Answer: He will have $1721.28. after 4 years.
Step-by-step explanation:
The formula we use to find the compounded amount A is :
, where P= principal value, r = rate of interest , t= time.
As per given , we have
P=$1500 , r=3.5%=0.035 , t= 4 years
Money he will have after 4 years = 
Hence, he will have $1721.28. after 4 years.
Answer:
<h3>THEY ARE CONGRUENT BY <em><u>ASA</u></em> TEST OF CONGRUENCE</h3>
Because there are parentheses we distribute the negative signs:
3 - 20i + (-14) - 6i + (-8) + 2i
Next combine like terms:
3 + (-14) + (-8) and -20i - 6i + 2i
-19 -24i
Hello there i hope you are having a great day :) Your question: Suppose 21% of people own a dog. If you pick two people at random, then what is the probability that they both own a dog?
1) 21% own a dog so you would do 21/100 = 0.21 this would equal the first person now the second person you would do 21/100 = 0.21
2) now you would multiply it so 0.21 x 0.21 = 0.0441 the that would be your answer.
Hopefully that helps you ❤
