You can put this solution on YOUR website!
P(2 white balls) = P(white ball AND white ball) = P(white ball)*P(white ball) = (10/50)(10/50) = 100/2500 = 1/25 = 0.04\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So the probability is 1/25 which is a 4% chance. \n" ); document.write( "
