In a class of 31 student,16 play football,12play table tennis and 5 play both games,find the number of student who play at least one of the game
To find the number of students who play at least one game, we need to add the number of students who play football and the number of students who play table tennis, and then subtract the number of students who play both games, since they are counted twice.
Number of students who play football = 16
Number of students who play table tennis = 12
Number of students who play both games = 5
Number of students who play at least one game = 16 + 12 - 5 = 23
Therefore, 23 students play at least one game.
To find the number of students who play at least one of the games, we need to add the number of students who play football and the number of students who play table tennis, and then subtract the number of students who play both games.
Number of students who play football = 16
Number of students who play table tennis = 12
Number of students who play both games = 5
To find the number of students who play at least one game, we can use the Inclusion-Exclusion principle:
Number of students who play at least one game = (Number of students who play football) + (Number of students who play table tennis) - (Number of students who play both games)
= 16 + 12 - 5
= 23
Therefore, there are 23 students who play at least one of the games.
