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:
12 3/4 hours
Step-by-step explanation:
Jack spends 1 1/2 times as long on his homework as Jill .
Jill spends 8 1/2 in doing his home work .
Time spent by jack in doing his homework is jacks time multiplied by Jill’s
That’s
1 1/2 x 8 1/2
Change to improper fractions.
We have,
3/2 x 17/2
Multiply through
51/4 = 12 3/4
Jack spends 12 3/4 hours in doing his homework
When it says 7 more than a number equals 21, the "more than" is addition, a number is x (because it's the unknown number). So this one is x+7=21.
When it says 39 less than a number is 21. "Less than" means to subtract. The 39 is less than x, so it's x-39=21.
8 times a certain number increased by 1 is 65. Break it down, first 8 times a number, so it's 8*x or 8x. Then we add 1 to that, so it's 8x+1=65.
5 times some number decreased by 2 times the number is 42. Decreased by is subtraction. So it's 5x-2x=42.
When you look for the key words increased by (add), more than (add), multiplied by, times, less than (subtract), decreased by (subtract), is (equal sign), they will help determine what you need to do.
I hope this gives you a little more understanding. Good luck with it! :)
