Question 1067742
a)   There are 2 possible outcomes on each flip, and {{{2^3}}} outcomes on 3 flips, so the sample space is :
{HHH, HHT, HTH, HTT, THH, THT, TTH, TTT}

b)  Not sure what the question is, do you mean {{{2^3= 8}}} possible outcomes?
c)  Three heads can happen in 1 way, divide this by the number in (b) to get the probability.
d)  Exactly two tails can happen in 3 ways.  Again, divide by number in (b).
e)  Left as an exercise.
f)   Left as an exercise.
