A market researcher wants to determine whether a new model of a personal computer that had been advertised on a late-night talk show had achieved more brand-name recognition among people who watched the show regularly than among people who did not. After conducting a survey, it was found that 12% of all people both watched the show regularly and could correctly identify the product. Also, 13% of all people regularly watched the show and 39% of all people could correctly identify the product Define a pair of random variables as shown below. Complete parts (a) through (c) X=1 if regularly watch the show Y=1 if product correctly identified a Find the joint probability function of X and Y X 0 (Do not round.) 0 X=0 otherwise Y=0 otherwise 1
