Final answer:
55% of the people in the group like to play volleyball only. To find the percentage of people who like to play volleyball only, subtract the number of people who like to play both volleyball and football, as well as those who like to play neither game, from the total number of people who like to play volleyball
Step-by-step explanation:
To find the percentage of people who like to play volleyball only, we need to subtract the number of people who like to play both volleyball and football, as well as those who like to play neither game, from the total number of people who like to play volleyball.
So, the percentage can be calculated as: (120 - 12.5 - 25) / 150 x 100% = 82.5 / 150 x 100% = 55%
Therefore, 55% of the people in the group like to play volleyball only.
