Answer 1

Answer:

7/8

the total sample.piece we can get is 8

Step-by-step explanation:

Answer 2

Answer:

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
