3)Calculate above mentioned probabilities if first card is not replaced?
Q:2 A information source produces 0's and 1's with probabilities of 0.3 and 0.7 respectively.The output of the source is transmitted via channel that has a probability of error(turning 1 into 0 and 0 into 1 ) equal to 0.2
1) What is the probability that at the output a 1 is observed .
2) What is the probability that a 1 was the output of the source if the output of the channel a 1 is observed.

Q:1 A card is drawn from a deck of 52 cards,then replaced and a second card is drawn
1)What is the probability of drawing same card on the 2nd draw?:: (1/52)
---------------
2)What is the probability of drawing a 3 of hearts and then a 4 of spades?
:: (1/52)^2
---------------
3)Calculate above mentioned probabilities if first card is not replaced?
:: 0 and (1/52)(1/51)
=====================
Q:2 An information source produces 0's and 1's with probabilities of 0.3 and 0.7 respectively.
The output of the source is transmitted via channel that has a probability of error(turning 1 into 0 and 0 into 1 ) equal to 0.2
1) What is the probability that at the output a 1 is observed.::0.7
------
2) What is the probability that a 1 was the output of the source if the output of the channel a 1 is observed.:: P(1 | 1 transmitted) = 0.8
