Total psbl outcomes => HHH, HHT, HTH, THH, TTT, TTH, THT, HTT = 2³ = 8
where H = head
T = tail
P(e) = fav outcomes / total outcomes
1) fav outcomes => HHH = 1
P(e) = 1/8
2) fav outcomes => TTT, TTH, THT, HTT = 4
P (e) = 4/8 = 1/2 = 0.5
atleast two tails means 2 or more than two tails , not less than that....
