You can put this solution on YOUR website!
p(a or b) = p(a) + p(b) - p(a and b)
\n" ); document.write( "you get:
\n" ); document.write( ".36 = .32 + .48 - p(a and b)
\n" ); document.write( "solve for p(a and b) to get:
\n" ); document.write( "p(a and b) = .32 + .48 - .36 = .44
\n" ); document.write( "you get:
\n" ); document.write( "p(a or b) = p(a) + p(b) - p(a and b) becomes .36 = .32 + .48 - .44 = .36, confirming the arithmetic is correct.
