sample space = 8
so the probability of getting 2 tails will be 4/8
so .1/2 is the answer...

Coins tossed = 3
No of Possible Outcomes = 8
They are,
(H,H,H) (T,T,T) (H,T,H) (T,H,T) (H,H,T) (T,T,H) (H,T,T) (T,H,H)
__________________________________________________________
Case I : At most 2 tails
No of needed Outcomes(2 tails) = 3
Probability that the coin tossed give 2 tails = 3/8
_________________________________________________________
Case II : At least 2 tails
No of needed Outcomes(2 tails) = 4
Probability that the coin tossed give 2 tails = 4/8 = 1/2
No of Possible Outcomes = 8
They are,
(H,H,H) (T,T,T) (H,T,H) (T,H,T) (H,H,T) (T,T,H) (H,T,T) (T,H,H)
