A message is combined by the symbols 0, 1, 2 and 3. Assume that P{0}=1/3, P{1}=3/8, P{2}=1/8 and P{3}=1/6, it is obviously obtained that the self-information of the symbols 0 is ______________, the self-information of the symbols 1 is ______________,the self-information of the symbols 2 is ______________ and the self-information of the symbols 3 is ______________. When we get a message with a single symbol, the symbol information is_______________. (two decimal numbers,e.t.c., 3.34bit)
