Answer 1

Question is incomplete: Here we can take some cases to solve the problem

Case 1: A coin is tossed once

Sample space ($S_1$ ) = {H, T}

No. of head appear at least once = 1 times

Case 2: A coin is tossed twice

Sample space ($S_2$ ) = {HH, HT, TH, TT}

No. of heads appear at least once = 3 times

Case 3: A coin is tossed thrice

Sample space ($S_2$ ) = {HHH, HHT, HTH,THH, TTT, TTH, THT, HTT}

No. of heads appear at least once = 7 times
