问题 The uncertainty of an event is measured by its probability of occurrence and is inversely proportional to that．The more uncertain an event is，the more information is required to resolve uncertainty of that event．The amount of information is measured in(   )．
选项 A、possibility
B、bits
C、bps
D、probability
答案B
解析 Information cannot be predicted and resolves uncertainty．The uncertainty of an event is measured by its probability of occurrence and is inversely proportional to that．The more uncertain an event，the more information is required to resolve uncertainty of that event．The amount Of information IS measured in bits．Example：intbrmation In one”／alr”coin flip：log2(2／1)=1 bit，and in two fair coin flips is log2(4／1)=2 bits．
