    Answer:97/125

    Step-by-step explanation:

    "As illustrated in the Venn diagram,

    We let

    U=[The total number of people at the sport center]

    This implies that,

    n (U) = 125

    G=[Those who use the gym]

    This implies that,

    n (G) = 59

    P=[Those who use the pool]

    This implies that,

    n (P) = 70

    T=[Those who use the track]

    This implies that,

    n (T) = 55

    a=[Those who use the gym only]

    This implies that,

    n (a) = 59 - (6+11+19) = 59-36=23

    b=[Those who use the pool only]

    This implies that,

    n (b) = 70 - (6+19+24) = 70-49=21

    c=[Those who use the track only]

    This implies that,

    n (c) = 55 - (6+24+11) = 55-31=14

    Also, number of people who use gym and track=11+23+19+6+14+24=97"
