Hey there!
If we have two white marbles and seven purple marbles, our first probability is out of nine.
First of all, we have the probability of selecting a purple marble, 7/9.
Now, if we do not replace it, there are only eight marbles left. Therefore, getting a white marble is 2/8, or 1/4.
We multiply these probabilities together to get our answer to a.
7/9(1/4)= 7/36
a. 7/36
Now, let's do b. We have 2/9, and then 1/8, giving us 1/36.
b. 1/36
Now, let's calculate selecting two purple to help us with C.
We have 7/9, and then 6/8, or 3/4.
7/9(3/4)= 7/12
Since there is a majority of purple marbles, there is a C) greater probability of selecting two purple marbles in a row.
I hope this helps!
You’re learning the definition of the derivative aren’t you. Just plug in x+h and do FOIL. Then multiply each term by -3 because of -3 infront of the square.
-3(x+h)^2 - 2(x+h) +4
-3[x^2 + 2xh + h^2] - 2x - 2h + 4
-3x^2 - 6xh - 3h^2 - 2x - 2h + 4
Your answer is D

Answer:
31/100
Step-by-step explanation:
A percentage can be expressed as a fraction by making use of the fact that the % symbol is essentially equivalent to /100.
31% = 31/100
