    Hi

    This question was given to my niece in year 10 maths.

    Would someone please be able to review the problem as stated below and
    provide me with your answers to the questions asked?

    I believe that it is inproperly stated and am looking for a fresh
    opinion as I do not agree with her teacher's "correct" answer.

    Thanks

    c) the probability of getting at least 2 tails
