\n" ); document.write( "\n" ); document.write( "Part (a)\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "There are 4 copies of cards with the label \"3\" (one for each suit).
\n" ); document.write( "Since Sara is not replacing the 3 of hearts she selects, there are 4-1 = 3 copies remaining. This is out of 52-1 = 51 cards.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "3/51 = (1*3)/(17*3) = 1/17 is the probability of another 3 being selected if the first card is not replaced.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "------------------------------------
\n" ); document.write( "Part (b)\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "There are 52 cards in a deck.
\n" ); document.write( "52/4 = 13 of which are hearts
\n" ); document.write( "(ace, 2 through 10, jack, queen, king)
\n" ); document.write( "This excludes jokers.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "If 3 of hearts is the first card, and not put back or replaced, then there would be 13-1 = 12 hearts remaining out of 52-1 = 51 cards
\n" ); document.write( "12/51 = (4*3)/(17*3) = 4/17 is the answer to part (b)\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "------------------------------------
\n" ); document.write( "Part (c)\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "There are 13 clubs out of 52-1 = 51 cards remaining.
\n" ); document.write( "This leads directly to 13/51 which cannot be reduced further.
\n" ); document.write( "Note I did not subtract 1 from the clubs since the sets \"hearts\" and \"clubs\" are mutually exclusive. There's no overlap.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "------------------------------------
\n" ); document.write( "Part (d)\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "There are 4 copies of 7 out of 52-1 = 51 cards remaining.
\n" ); document.write( "Therefore the answer is 4/51
