You are given the task of testing a wireless link between Delhi and Hyderabad. You do so by
sending many bits (each bit is either 0 or 1) over the link from Delhi to Hyderabad. A receiver at Hyderabad
records, for every sent bit, its estimate (0 or 1) of what was sent. At the end of the experiment you come up
with the following data. You find that 90% of the bits sent are received correctly. You also find that amongst the
correctly received bits, 70% of the bits were sent as 1. Also, 30% of the wrongly received bits were sent as 1.
The cost of sending a bit that is correctly received is 100 and that of sending a bit that is wrongly received is
50. What is the expected cost of sending a bit over the link?
