JEE Math Practice Question
Let a computer program generate only the digits 0 and 1 to form a string of binary numbers with probability of occurrence of 0 at even places be $${1 \over 2}$$ and probability of occurrence of 0 at the odd place be $${1 \over 3}$$. Then the probability that '10' is followed by '01' is equal to :
- A.$${1 \over 18}$$
- B.$${1 \over 3}$$
- C.$${1 \over 9}$$
- D.$${1 \over 6}$$
