Multiple choice

A source emits bit 0 with probability 1/3 and bit 1 with probability 2/3. The emitted bits are communicated to the receiver. The receiver decides for either 0 or 1 based on the received value R. It is given that the conditional density functions of R are

fR/0 (r) = and fR/1 (r) =

The minimum decision error probability is

  1. 0
  2. $\frac{1}{12}$
  3. $\frac{1}{9}$
  4. $\frac{1}{6}$
