document.write( "Hi
\n" );
document.write( "a) P(A|B) = P(A and B)/P(B)       |P(A)=0.6, P(B)=0.4, P(A intersect B)=0.2 
\n" );
document.write( "substitute
\n" );
document.write( "P(A|B) = .2/.4 =    
\n" );
document.write( "b) P(A and B) = P(A) + P(B) - P(A OR B)  |P(A)=0.4, P(B)=0.5, P(A union B)=0.6
\n" );
document.write( "substitute 
\n" );
document.write( "P(A and B) =  .4 + .5 - .6 = .3
\n" );
document.write( "substitute
\n" );
document.write( "P(B|A)=  P(A and B)/P(A) = .3/.4 = .75   0R 3/4 \n" );
document.write( "

\n" );
