    Part i) it is simply the probability of getting two sixes, which can happen 3 different ways plus the probability of getting 3 sixes because it says at least two sixes meaning 2 or greater. So you get 3x (1/6 x1/6 x5/6) + (1/6)^3.
    Part iii is simply 1/6 x 5/6 ( because you have 5 remaining digits to choose from) x4/6 ( because you have 4 remaining digits to choose from). This can happen 6 different ways so we multiply by 6.
    Thank you for part i and iii

    Would it not just be 1 minus the answer from part (c)? Having at least two people born under the same star sign just means not having all five people born under the same star sign.

    Thus, p = 1 - (55/144) = 89/144 = 0.618 (3 s.f.)
