A roulette wheel has 18 red, 18 black, and 2 green slots. one dollar bet on black wins one dollar. find the expected value for a $10 bet on black.
\n" ); document.write( "
\r\n" );
document.write( "18 successful slots out out of 38, a probability of winning is \"18%2F38\" = \"9%2F19\"\r\n" );
document.write( "\r\n" );
document.write( "Expected value for the player = (Amount won)(Probability of winning) = $10\"%289%2F19%29\" = $4.74\r\n" );
document.write( "\r\n" );
document.write( "Therefore the expected value for the casino is $10.00-$4.74 = $5.26 \r\n" );
document.write( "\r\n" );
document.write( "if 1000 people each make a $10 bet on black, how much does the casino expect to make?\r\n" );
document.write( "\r\n" );
document.write( "$5.26×1000 = $5260\r\n" );
