For mutually exclusive events (a die cannot show a 3 and a 4 at the same time):
\n" ); document.write( "P(A or B) = P(A) + P(B), so
\n" ); document.write( "P(3 or 4) = P(3) + P(4)\r
\n" ); document.write( "\n" ); document.write( "P(3) = 2/12 = 1/6 Since there are two 3's in 12 numbers on two dice.
\n" ); document.write( "P(4) = 2/12 = 1/6 Since there are two 4's in 12 numbers on two dice.\r
\n" ); document.write( "\n" ); document.write( "P(3) + P(4) = 1/6 + 1/6 = 2/6 = 1/3\r
\n" ); document.write( "\n" ); document.write( "The probability of throwing a 3 or a 4 on a single throw of two dice is 1/3 \n" ); document.write( "

\n" );
