Answer:
A coin can only get heads or tails. So you have 1/2 chance of getting either heads or tails. Well simplify tails to T and heads to H. So you have a 7/8 chance that you will have at least one tails.

Answer:
3/8
Step-by-step explanation:
Probability,P= favorable outcome/total Outcomes
OUTCOMES CAN BE = (H,H,H), (H,H,T), (HTH),(THH), (H,T,T),(T,H,T), (T,T,H), (T,T,T) = 8
Favourable Outcomes = (H,H,T), (HTH),(THH)= 3
Therefore,
P= 3/8
