    Mr F says: Try drawing a tree diagram.

    four friends two females and two males are playing contact bridge. partners are randomly assigned. what is the probability that the two females will be partners for the first game?

    Mr F says: The possibilities are:

    M1 M2, F1 F2
    M1 F1, M2 F2
    M1 F2, M2 F1

    laura, dave, monique, marcus and sarah are going to a party. what is the probablity that two of the girls will arrive first?

    Mr F says: First list the possible orders:

    Laura, Dave, Monique, Marcus, Sarah.

    Laura, Dave, Monique, Sarah, Marcus

    etc.

    Pr = (no. of favourable outcomes)/(total number of outcomes).
