You take 50 times .082 which is 8.2% in decimal form to get 4.1
4.75/0.25=19
200*19=3800
It will take Tammy 3800 steps
It's actually PEMDAS. P is for parenthesis. E is for exponents. M is for multiplication. D is for division. A is for Addition. S is for subtraction.
Here's an example that includes all of these:
(6-2)²x4/2+6-4
P first.
(6-2) = 4
(4)²x4/2+6-4
Now E.
(4)² = 16
16x4/2+6-4
Then M.
16x4 = 64
64/2+6-4
Next is D.
64/2 = 32
32+6-4
Now A.
32+6 = 38
38-4
And finally, S.
38-4 = 34.

The probability that any given car will have a brake failure if it is make a is 0.0065%
<h3>How to determine the probability?</h3>
The complete question is added as an attachment
From the table in the question, we have:
P(Brake failure|car a) = 0.0065%
The above represents the required conditional probability
Hence, the probability that any given car will have a brake failure if it is make a is 0.0065%
