Possible samples are as follows

• HHH
• HTH
• HHT
• THH
• TTH
• THT
• HTT
• TTT

Let A be the event of getting one head.

Let B be the event of getting no head.

Favourable outcome for a = {TTH, THT, HTT}

Favourable outcome for B = {TTT} Total no. of outcomes = 8

Required probability of getting one head + probability of getting no head

P(A) = ⅜

P(B) = ⅛

P(A) + P(B) = ⅜ + ⅛ = ½
