SUMMARY

The discussion centers on the application of probability theory, specifically the calculation of the union and intersection of events. Waqas, a BSCS student from Karachi University, seeks clarification on finding P(A ∪ B) and P(A ∩ B) given two quantities, A and B. The correct formula provided is P(A ∪ B) = P(A) + P(B) - P(A ∩ B), emphasizing the importance of understanding event probabilities rather than treating quantities as standalone values.

PREREQUISITES
  • Basic understanding of probability theory
  • Familiarity with event notation (e.g., A ∪ B, A ∩ B)
  • Knowledge of how to calculate probabilities of events
  • Experience with statistical concepts
NEXT STEPS
  • Study the principles of set theory in probability
  • Learn about conditional probability and its applications
  • Explore the concept of independent and dependent events
  • Practice solving probability problems using real-world scenarios
USEFUL FOR

Students of statistics, mathematics enthusiasts, and anyone looking to strengthen their understanding of probability concepts and calculations.

hello, my name is waqas, a new member from Pakistan. I am a student of BSCS Karachi University. I am facing lot much problem in understanding Probability (Stats).

I want to ask a question that..
If we have A some quantity like 10 and B say 15 and if we have to find P(AUB) then how can we find AnB?
 
Physics news on Phys.org
probabilities apply to events not quantities like that.

i think you want

P(AuB)=P(A)+P(B)-P(AnB)
