bulgar [2K]
<h3>Answer:</h3>

\huge{\boxed{72}}

<h3>Explanation:</h3>

First, find the total number of apples.  6*1200=7200

Now, multiply this by the probability of picking a rotten apple, which is \frac{1}{100}.  This is also the same as dividing by 100, or moving the decimal point two places to the left.  7200*\frac{1}{100}=72

This means that based on the probability given, 72 rotten apples will be picked.
