HELPPPP PLEASEE :A survey was conducted among 100 students of age groups 7-12 years and 13-18 years to find their favorite book genre. The students had to select any one genre out of detective, adventure, and biography. Out of the 50 students in the age group 7-12 years who participated in the survey, 23 liked adventure or biography. The total number of students of both age groups who liked detective books was 28. Using a two-way table, compute the total number of students in the age group 13-18 years who liked adventure or biography. 23 27 49 51

    good try but no The total number of students of both age groups who liked detective books was 28. the total of d is 28, so the total of the column is 28 |dw:1432951259190:dw| and we can use x and y for some unknowns. x is what we want to know, how do you spose we find it now?

    x + 23 = y y + 28 = 100, therefore x + 23 + 28 = 100, solve for x
