Possible number of outcomes is 2³=8.
Favourable outcomes are 3.
Probability is 3/8

H = head
T = tail
so sample space = {HHH,HHT,HTH,HTT,THH,THT,TTH,TTT}
SO TOTAL OUTCOMES = 8
SO TOTAL EVENT = 3
SO PROBABILITY = NO OF POSSIBLE EVENTS /TOTAL OUTCOMES
= 3/8
T = tail
so sample space = {HHH,HHT,HTH,HTT,THH,THT,TTH,TTT}
