I would say origin, but it's a hard choice.

I'm pretty sure it's origin, because the rest don't make sense to me.

If a denotes some event, what does upper a overbara denote? if p(a)equals=0.9930.993, what is the value of p(upper a overba

masya89 [10]

P(A) = 0.993 is the probability of event A
_
P(A) is the probability of not A (note that I am trying to place a bar over A. I hope you can see it, else it is because the editor did not show it as I intended)

Then, use the fact that the probability of A plus the probability not A is equal to 1:
                  _
=> P(A) + P(A) = 1
       _
=> P(A) = 1 - P(A) = 1 - 0.993 = 0.007

So, the answers are:
      _
1) P(A) = 0.07
             _
2) Yes, A is unlikely because its probability is very low.

How to do the problem

MrMuchimi

Order of operations are:
1. Parentheses (simplify inside 'em)
2. Exponents
3. Multiplication and Division (from left to right)
4. Addition and Subtraction (from left to right)

So, on your first one:
Parentheses first:
8(3+4)-2*8/(5-3)
8(7)-2*8/(2)

There are no exponents so multiplication and division:
56-16/2
56-8

Finally, addition and subtraction:
56-8=48

Your second problem is a bit more complicated but follows the same rules:
 $( 8^{2}+(13-4) ^{2} )/5$

Parentheses first:
 $( 8^{2}+ 9^{2})/5)$

Now, exponents. Even though they are inside parentheses, we can't go further until we simply those.
(64+81)/5

Now back to parentheses:
(145)/5

Division:
145/5=29

Hope that helps
