Answer:

head= 8/27

tail= 1/9

Step-by-step explanation:

Suppose, probability of head = q

probability of tail = p

Given that probability of head = 2 probability of tail

q = 2p

1-p = 2p

1 = 3p

p = 1/3

q = 1 - p

q = 1 - 1/3

q = 2/3

hence, for 3 independent tosses of the coin probability of head

= (2/3)³

= 8/27

and for 3 independent tosses of the coin probability of tail

= (1/3)³

= 1/9
