Answer:
P(-A) = 0.388
Step-by-step explanation:
By the <u> PROBABILITY POSTULATE: </u>
P(A) + P(not A) = 1
Here, P(A) = 0.612
So, P(not A) = P(-A) = 1 - 0.612 = 0.388
⇒P(-A) = 0.388
Answer:
2
Step-by-step explanation:
You can rewrite thosee two equations as -9x+12=-6, because f(x)=f(x)
Now isolate x
-9x+12=-6
-9x+12-12=-6-12 (subtract 12, subtraction property of equality)
-9x=-6-12
-9x=-18 (simplify)
-9x/-9=-18/-9 (divide by 9, division property of equality)
x=2
