B. 1/2
C. 3/4
D. 1/4
HH,HT,TT,TH
As evident from above sample space,the probability of finding exactly one Head 2\4 I.E 1\2
so the answer is B
Option B. is correct.
Possible chances of occurring an event are known as the probability of that event.
Sample space for tossing two coins is :
( {H,H} , {H,T} , {T,T} , {T,H} )
Probability of an event =
Exactly one head appeared 2 times i.e., {H,T} or {T,H}
Thus, Favourable outcomes = 2
Total outcomes = 4
P (Exactly one head) =
