Two way tables- Marginal and conditional probabilities 6. According to the consumer Electronics Manufacturers Association, 31% of all U.S households have a fax machine and 47% have only personal computer. Suppose 19% of all U.S. have both a fax machine and a personal computer. i ) Compute the (2-way table)joint probability matrix. Use proper labels for rows and columns. ii) What is the probability that a household have either a fax machine or a personal computer? Conditional Probability formula for two events P(A among B) also P( A given B ) is same as P(A/B) P(A/ B) = P(A and B) P(B) iii) What is the conditional probability that a household have a fax machine given that does have a personal computer? iv) What is the conditional probability that a household does have personal computer given that he has a fax machine
