A survey was conducted among 100 students of age groups 7−12 years and 13−18 years to find their favorite book genre. The studen
ts 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
Here's what you got to do to solve is finding the total amount of people ages 13-18 that like all three genres. and from there you need to find the total of 13-18 years that like biology or adventure. and then subtract both totals and you should get your answer.
