Question

A coin is tossed three times. then the probability that at least one tail occurs
​

Answer 1

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 2

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
