if we toss a coin three times
then events possible to come ----
(T, T, T) , (T, T, H) , (T, H, H) , (H, H, H),
(H, H, T), (H, T, T), (H, T, H), (T, H, T)
hence ,
n (S) =8
n (E) =1
we know ,
p (E) =n (E)/n (S) =1/8
hence ,
P (E) =1/8 (ans )
then events possible to come ----
(T, T, T) , (T, T, H) , (T, H, H) , (H, H, H),
(H, H, T), (H, T, T), (H, T, H), (T, H, T)
hence ,
n (S) =8
n (E) =1
we know ,
p (E) =n (E)/n (S) =1/8
hence ,
P (E) =1/8 (ans )
