Answer:
The probability of randomly selecting someone who does not believe that statistics teachers know the true meaning of life is 0.426.
Step-by-step explanation:
Let <em>X</em> = number of Americans who believe that statistics teachers know the true meaning of life.
The probability of the random variable <em>X</em> is,
P (X) = 0.574
The event of a person not believing that statistics teachers know the true meaning of life is the complement of the event <em>X</em>.
The probability of the complement of an event, <em>E</em> is the probability of that event not happening.

Compute the value of
as follows:

Thus, the probability of randomly selecting someone who does not believe that statistics teachers know the true meaning of life is 0.426.
3,000,000 + 20,000 + 9,000 + 200 + 50 + 1
I’m guessing you want to find out (n).
That’s what I did anyway.
The answer is: n=5
Step 1: Subtract 5n from both sides.

1.8
n
+
9
=
0
Step 2: Subtract 9 from both sides.
−

Step 3: Divide both sides by -1.8.
−
