Suppose you need to send 38 messages, each of which can be one of the 16 possibilities (as above), On average 75% of the messages is M11, How many bits are required to send those 38 messages? b. Suppose you need to send 50 messages, each of which can be one of the 16 possibilities (as above), On average 20 of the messages are M11, 15 of the messages are Ms and 15 of the messages are M10, How many bits are required to send those 38 messages? c. Suppose you need to send 38 messages, each of which can be one of the 16 possibilities (as above), On average 75% of the messages is M11, How many bits are required to send those 38 messages
