Hello !
It is sure that tail comes 380 times , out of 600 chances ,
then unknown results = 600 - 380 = 220 = Sample space
(a)
The chances of getting a head (H)= 1/2 × Sample space = 1/2×220 = 110

The probability of getting a head = Total chances oh head(H)/Sample space = 110 / 220 = 1/2
 (b)
The probability of getting a tail = 1 - 1/2 = 1/2
I hope my answer is correct !
Please mark as the best if u are satisfied !
Thankyou!
