document.write( "Question 1130332: We can calculate odds if we know the probability. But we can also go the other way. Suppose the odds in favor of an event are 3 to 2. We can interpret this as saying that there are three (equally likely) favorable outcomes and two unfavorable ones. That is a total of five outcomes. So the probability of the event occurring is 3/5. In general, if the odds in favor are p to q, then the probability is

5:7 are odds against
\n" ); document.write( "7:5 are the odds for
\n" ); document.write( "\"+7%2F%28+7%2B5+%29+=+7%2F12+\"
\n" ); document.write( "\"+7%2F12+=+.583+\"
\n" ); document.write( "is the P that event will occur
\n" ); document.write( "---------------------------------
\n" ); document.write( "5:7 are odds against
\n" ); document.write( "\"+5%2F12+=+.417+\"
\n" ); document.write( "is P event will not happen
