Jeffrey, R (2002) Subjective Probability: The real thing. An excellent text that sufficiently covers subjective probability and probability theory. Well worth your time to read so you understand basic probability theory.
Kroese, D.P. (2018) A Short Introduction to Probability. Another excellent primer on probability theory with some code examples (note: not R but looks very similar).
Gravner, J. (2011). Lecture Notes for Introductory Probability. A rather in-depth look at probability from Gravner's lectures at UC Davis.
Carnegie Mellon's probability and statistics (open and free) series
Black, K. (2015). R Tutorial. Kelly was generous enough to offer her introductory to R materials to the world. I found the notes to be extremely useful for most novices.

New Python users ought to consult Allen's Think Python
My Google Drive collection of published articles.
Downey, A.B. Think Bayes. A book devoted to Bayesian thinking but code in Python. Well worth perusing - especially later in the semester when we try to run some models in Python.
Gelman, A. (2008). Objections to Bayesian statistics. Bayesian Analysis, 3(3), 445-449.
