Answer:
<h3>The event
denotes the complement of event A.</h3><h3>The value of
is 0.001</h3>
Step-by-step explanation:
Given that A denotes some event .
And also given that P(A)=0.999
<h3>To find the value of
:</h3>
Here the event denotes the complement of event A Therefore contains all the events that does not occur in A.
We know that the total probability is 1
So we have that
Hence the complement of event A is 
<h3>Therefore the value is
</h3>
Answer:
Should be 39 years.
there is 12 inches in a foot. and if the tree grows 4 inches every year, then in 3 years the tree would be 1 foot. 13 x 3 = 39, thus proving that in 39 years, it will be 13 feet tall. I may be wrong but this sounds correct.
The estimated probability would be 0.1... I had this test yesterday. hope this helps
a+b+c=0
[(a+b+c)^2=a^2+b^2+c^2+2ab+2ac+2bc]
[a^2+b^2+c^2+2ab+2ac+2bc=0]
[a^2+b^2+c^2=-(2ab+2ac+2bc)]
[a^2+b^2+c^2=-2(ab+ac+bc)] (i)
also
[a=-b-c]
[a^2=-ab-ac] (ii)
[-c=a+b]
[-bc=ab+b^2] (iii)
adding (ii) and (iii) ,we have
[a^2-bc=b^2-ac] (iv)
devide (i) by (iv)
[(a^2+b^2+c^2)/(a^2-bc)=(-2(ab+bc+ca))/(b^2-ac)]
