What is the probability that when a coin is tossed twice successively the outcome would be one head and one tail?
A
1/4
B
1/2
C
2/3
D
1
Correct Option:
B
Explanation
Two coin tosses produce four equally likely outcomes: HH, HT, TH, TT. Exactly one head and one tail occurs in HT and TH, i.e. 2 outcomes out of 4. Thus, probability =2/4=1/2.
