A coin is tossed 850 times with head turning up 355 times. If coin is tossed again, compute the probability for getting
(1) head
(2) tail

Answer 1

Hola amigo !
______________________________________________________________
A coin is tossed 850 times 
Outcomes of head = 355 times 
Outcomes of tail    =  495 times
______________________________________________________________
Probability of head = 355/850= 71/170
Probability of Tail    =  495/850=99/170

Answer 2

Hi friend ,

1. Total outcome = 850
Favourable outcome = 355
P( Head) = Favourable outcome / Total outcome
P( head) = 355/850
P( head )= 71/170

2. let the p(tail) be x

71/170+x = 1
x = 1-71/170
x= 170-71/170
x= 99/170
P( tail ) = 99/170
