Explanation:

Step1: Analyze the stem-and-leaf plot

The stem represents the tens place and the leaf represents the ones place. For the number 20, the stem should be 2 (since \(2\times10 = 20\)) and the leaf should be 0 (since \(0\times1 = 0\), and \(20=2\times10 + 0\times1\)).

Step2: Count the number of leaves with value 0 in the stem 2 row

Looking at the stem 2 row: the leaves are 0, 0, 0, 1, 4, 6. We count the number of 0s. There are 3 zeros.
