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.

Help me plz it’s important
nirvana33 [79]

Answer:

C

Step-by-step explanation:

The correlation is becoming stronger, with a negative direction.

The closer a number is to the zero in the number line when its negative the more value it has.

Now if the number is negative and its away from zero in the number line  the less value it has.
