Just make sure to add a column for "0" and add a 5.
If you're confused on stem and leaf plot in general, just remember the stem (of the main part of any plant) is the main part of the flower. So in this case, the stem is the main part of the number in the tens spot.
The leaf (the less important part), kind of "dangles" there, and that'll be the second number.
I can try my best to help you but if I am wrong I am sorry, Stem: 0,1,2,3 and leaf: 5, 0025699, 26, 7779. The next one part b should be mean: 21.7, mode: 10,19, Median: 19, Range: 34
The two "types of probability" are: 1) interpretation by ratios, classical interpretation; interpretation by success, frequentist interpretation. The third one is called subjective interpretation.
