Question

If you flip three fair coins, what is the probability that you'll get all three heads?

Answer 1

Answer:

1/8

Step-by-step explanation:

(1/2)×(1/2)×(1/2)

= 1/8

Answer 2

Answer:

1/8

Step-by-step explanation:

n(s)={HHH,HHT,HTH,THH,TTT,TTH,THT,HTT}

n(s)=8

now let A be the event of getting all three as heads

therefore, n(A)=1

p(A)=n(A)/n(s)=1/8
