Calculate the probability of drawing 4 red balls and then 4 green balls as shown;
P(4R+4G)=(
)(
)(
)(
)(
)(
)(
)(
)
P(4R+4G)=0.00308 chance
The denominators are decreasing as the balls get taken out.
Hope I helped :)

Apply distributive property 2(5 - 3x) multiply 2 * 5, and 2 * -3x, you will end up with 10 - 6x.

C
5*2x = 10x
5*4y = 20
Have a great day, good luck!
Since 1 batch is 2.5 cups and he needs to save 6.. what you'll do is subtract 16-6. The. You create a proportion.. You cross multiply then divide..
N J - the distance from Noe to Juliette;
Δ ABJ and Δ BCN are similar:
60 : 45 = 36 : CN
60 CN = 45 x 36
60 CN = 1620
CN = 1620 : 60
CN = 27 m;
DN = 27 + 45 = 72 m
After that we will use the Pythagorean theorem:
NJ ² = 96² + 72
NJ² = 9216 + 5186 = 14 400
NJ = √ 14 400
NJ = 120 m
Merci. Au revoir.
