Flip a coin has a probability of $\"1%2F2\"$ and it's independent so the probability of the marble problem was,
\n" ); document.write( " $\"P=P%5Bm%5D%2A%281%2F2%29=%2812%2F40%29=3%2F10\"$
\n" ); document.write( " $\"P%5Bm%5D=3%2F20\"$
\n" ); document.write( "Probability of choosing a white marble from the bag fits the bill.
