I have a problem that i cant figure out.
\n" ); document.write( "q. If the odds aginst event E are 2:5, what is the probability of a failure?
\n" ); document.write( "------
\n" ); document.write( "Definitions: odds against E = P(E')/P(E)
\n" ); document.write( "And P(E) + P(E') = 1
\n" ); document.write( "----------------------------------
\n" ); document.write( "Your DATA:
\n" ); document.write( "odds against = 2:5 = (2/7)/(5/7
\n" ); document.write( "So P(failure) = P(E') = 2/7
\n" ); document.write( "================
