1. In the communication system below the probability of transmitting (\"B\" before) symbols 1 an are: P(BI) = 0.7 and P(BO)=0.3. are: P(Al/BI) = 0.8 and P(AO/BI) = 0.2 At the receiver (\"A\", after), when symbol 1 is sent, the conditional probabilities of reception of 1 When symbol O is sent the conditional probabilities of reception of 0 or 1 are: a) Find the total probability of reception of symbol 1 P(AI) and the total probability of reception of P(A/BO) = 0.9 and P(A/BO) = 0.1 symbol O P(40) b) Find the probability of transmission of symbol 1 when symbol O is received, P/BI/ 40) and the probability of transmission of symbol o when symbol 1 is received, P(BO/AI) c) Find the total probability of error in reception B1 P(B1)=0.7 A1 P(A1/B1)=0.8 P(A/B1)=0.2 P(A1/BO)=0.1 P(A/BO)=0.9 AO BO P(BO)=0.3
