Study Notes
Probability Theory Aims and Meaning
- The aim of probability theory is to study chance events and their likelihood of occurrence.
- In the context of probability theory, the word 'probable' means likely to happen or occur.
Applications of Probability Theory
- Probability theory can be applied in various fields, including mathematics, statistics, engineering, physics, and finance.
Combinatorics and Probability
- The number of ways of selecting r objects out of n objects, where the order of selection is not important, is given by the combination formula: nCr = n! / (r!(n-r)!).
Real-World Applications
- Life insurance companies use the principles of probability to calculate the likelihood of events such as death, accidents, or natural disasters, in order to determine insurance premiums and policy payouts.
