    T1 = town1

    T2 = town2

    T3 = town3

    S = summer

    W = winter

    T = total

    T1 : S = 567; W = 87; T = 654

    T2: S = 345; W = 102; T = 447

    T3: S = 143; W = 158; T = 301

    T. 1055; 347; 1402

    joint relative frequency of those in Town 2 who take a summer vacation

    345 / 1402 = 0.246 or 25%.
