Basic Mathematics, combinatorics and calculus Knowledge.

Course Educational Objectives (CEO):

CEO 1 To equip the students with a working knowledge of probability, statistics, and modeling in the presence of uncertainties.
CEO 2 To understand the concept of hypothesis and significance tests
CEO 3 To help the students to develop an intuition and an interest for random phenomena and to introduce both theoretical issues and applications that may be useful in real life.

Course Outcomes: At the end of the course, the students will be able to:

MCA105.1 Distinguish between quantitative and categorical data
MCA105.2 Apply different statistical measures  on data
MCA105.3 Identify, formulate and solve problems
MCA105.4 Classify different types of Probability and their fundamental applications
