A number is selected at random from the set of 1,2,3,4,5,6,7,8,9,10.
\n" ); document.write( "Find:
\n" ); document.write( "P(even or power of 3) = P(even)+P(pwr of 3) = (5 + 3)/10 = 8/10
\n" ); document.write( "---------------------------\r
\n" ); document.write( "\n" ); document.write( "P(power of 2 or even) = P(pwr of 2) + P(even)-P(pwr 2 OR even)
\n" ); document.write( "= (4+5-3)/10 = 6/10
\n" ); document.write( "---------------------------\r
\n" ); document.write( "\n" ); document.write( "P (odd and prime) = 3/10
\n" ); document.write( "-----------------------------------\r
\n" ); document.write( "\n" ); document.write( "P(even or prime) = P(even)+P(prime)-P(even AND prime) = (5+3-1)/10 = 7/10
\n" ); document.write( "-----------------------------------\r
\n" ); document.write( "\n" ); document.write( "P(prime given odd) = P(prime AND odd)/P(odd) = (3/10)/(5/10) = 3/5
