The probabilities have to add to 1
\n" ); document.write( "If one is 0.06, the other has to be (1-0.06)=0.94\r
\n" ); document.write( "\n" ); document.write( "10C3=
\n" ); document.write( "10!/7!3!
\n" ); document.write( "10*9*8*7!/7!*3*2*1\r
\n" ); document.write( "\n" ); document.write( "The 7! cancel
\n" ); document.write( "10*9*8/3*2*1
\n" ); document.write( "720/6=120
\n" ); document.write( "=======
\n" ); document.write( "Three are 421 outcomes
\n" ); document.write( "A=39/421 =0.0926
\n" ); document.write( "C=258/421=0.6128
\n" ); document.write( "D=124/421=0.2945
\n" ); document.write( "That adds up to 0.9999.
\n" ); document.write( "======
\n" ); document.write( "632/(632+352)
