    for the first question i.e. sample space of 7 tosses of coin simply make the combinations of heads and tails their would be 128 combinations i.e. (2^7) e.g. for all heads make HHHHHHH for all tails TTTTTTT etc

    for probability question simply check that there are two no. i.e. 24 and 48 between 1-60 which i multiple of 6 & 8 both so the probablility would be 2/60.
