Hi James, The first probability is P(source|target) rather than P(target|source), so my guess is "! ) ," occurs only once in the second column, and maps to "! )" with probability 1. The third column holds p(target|source), so that's 0.125 + 0.5 = 0.625, which means there are probably more translation options for "! )" that cover the remaining 0.375, adding up to one.
