\n" ); document.write( "Carl claims to have so delicate a palate that he can tell by tasting from which brand
\n" ); document.write( "of juice L and R a given sample originated.
\n" ); document.write( "Carl is presented with eight cups filled by spinning a spinner with choices L and R .
\n" ); document.write( "p(L)= 1/4
\n" ); document.write( "p(R)= 3/4
\n" ); document.write( "Carl simply predicts the outcome which has the higher probability.
\n" ); document.write( "What is the probability that his guess will be correct?
\n" ); document.write( "~~~~~~~~~~~~~~~~\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "

\r\n" );
document.write( "Based on given info, you may think that of 8 cups, 2 are L and 6 are R.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "According to the problem, Carl always predicts R.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "So, his prediction is correct in 6 cases of 8.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Thus the probability he predicts correctly is   =  = 0.75 = 75%.    ANSWER\r\n" );
