in a class of 38 children,19 play tennis, 21 play squash and 10 play neither sport. (1)how many children play both sports?(2)how many children play only tennis

  • math -

    28 play some sport

    19+21-both=28
    both = 12

    tennis only = 19-12 = 7

  • math -

    Isn't 19 + 21 + 40 which is more than the amount of children in the class? Then you add 10 more that don't play it's 50. So how is the class total 38 as implied?
