About Professor Ledesma
I know that for many people, math is not their favorite subject, and sometimes, people say that they hate math. Many times, a person feels this way because of a bad math experience that they had in the past. I am here to help in any way possible to alleviate the frustration, stress, and anxiety that you may feel towards math and make the subject bearable, and maybe even make you a fan of math!

I started my teaching career in 2009 as a part-time mathematics teacher at California State University, Fullerton and carried on to become a part-time teacher at Cypress College and at Santiago Canyon College. Then in 2012, I was fortunate enough to be hired on as a full-time instructor here at Cypress College.
I have two little ones at home, my dogs Dexter and Sheldon, both named after a couple of my favorite television personalities. I am a homebody and love to relax at home, either watching my favorite television shows (some of which are Naruto, Archer, Impractical Jokers, The League, Big Bang Theory, The Vampire Diaries, etc…) or reading a great book (currently reading the A Song of Ice and Fire series).
MATH 120 C – Introduction to Probability and Statistics
In the Introduction to Probability and Statistics course, you will see many ways how mathematics can be applied and used in life. In this course, we learn to analyze the infinite data that is all around us, and make sense of it all. You can even use what you learn in this class to make big bucks in Las Vegas!
MATH 120 C: Introduction to Probability and Statistics
This course is an introduction to the elements of statistical analysis which includes an intuitive approach to the study of probability and probability distributions, measures of central tendency and dispersion, sampling techniques, parametric and non-parametric tests of hypotheses, point and interval estimation, linear regression and correlation. Applications to business, biological sciences, and social sciences are emphasized. Students will use computer software and/or graphing calculators for statistical analysis of various topics.
Since this is an online class, all of the lectures, homework and quizzes will be done online.You will have to come to campus for an in-person orientation on the first day of class and also to complete all exams and the final exam.
You will need the following materials by the first day of class:
- TI-83 or TI-84 graphing calculator
- Ruler and/or protractor
- Packaged Class Notes
- Access code to MyMathLab (this is the system where you will complete all of your homework assignments and quizzes)
- Six 882E Scantrons
Course Prerequisite: You must have completed either Math 040 (Intermediate Algebra) or Math 041 (Combined Algebra I and II) with a “C” or better.
Computer Skill Requirements: Know how to send and retrieve emails, basic keyboarding, and be able to navigate through MyMathLab.
All of your homework will be done through MyMathLab. Every section that we cover will have a homework assignment you must complete that will consist of approximately 20 questions. You will have unlimited attempts on each of your homework assignments.
All of your quizzes will be done through MyMathLab. You will have to complete a quiz for every section that we cover.
