Answer:
0.933 ; not independent
Step-by-step explanation:
Given :
A - made from natural polished wood
B - made from chrome accent
P(A) = 0.9
P(B) = 0.75
P(AnB) = 0.7
1.) probability of natural wood Giveb that it has chrome accent
P(A|B) = P(AnB) / P(B)
P(A|B) = 0.7 / 0.75
P(A|B) = 0.933
2.)
For an independent event :
P(AnB) = p(A) * p(B)
P(AnB) = 0.9 * 0.75 = 0.675
However, p(AnB) Given here is 0.7, thus the event aren't independent

Answer:
7/24
Step-by-step explanation:
there's a website called m.athway. that will give you the answer to any math problem.
Yep! 2/4, also known as 1/2 is larger than 2/5. You can verify this by getting a common denominator of 20 by multiplying the top and bottom of 2/4 by 5 and the top and bottom of 2/5 by 4, and asking yourself of this is true: Does 10/20=8/20? No it does not! Therefore 2/4 is bigger than 2/5!
