JEE Math Practice Question

Let E and F be two independent events. The probability that both E and F happen is $${1 \over {12}}$$ and the probability that neither E nor F happens is $${1 \over {2}}$$, then a value of $${{P\left( E \right)} \over {P\left( F \right)}}$$ is :

1. A.$${4 \over 3}$$
2. B.$${3 \over 2}$$
3. C.$${1 \over 3}$$
4. D.$${5 \over 12}$$
