in example: why not P(vegetarian | female) = 15/44??? The answer given in the video lecture is 15/47. similarly, why not P(vegetarian | male) = 29 /44 ??? answer given in the video lecture was 29 /53

Hey Muhammad, It's all in the conditional probability formula. First off, if we denote: A = vegeterian & B = female, then surely one can easily see (with the table you provided) that: P(A | B) = P(AB) / P(B) = 15 / (15 + 32) = 15/47 && P(B | A) = P(BA) ./ P(A) = 15 / (15 + 29) = 15/44. ----------------------------------------------------------- Following exactly the same logic and with the help of the table: P(vegetarian | female) = P(vegetarian AND female) / P(female) = 15 / 47, because 47 is the total number of females P(vegetarian | male) = P(vegetarian AND male) / P(male) = 29 / 53, because 53 is the total number of males Hope that's all clarified now!
