\n" ); document.write( "Hi,
\n" ); document.write( "p(note right= .99, n = 60
\n" ); document.write( "P(x=60) = binompdf(60, .99, 60).
\n" ); document.write( "P(x=59) = binompdf(60, .99, 59).
\n" ); document.write( "P(x=58) = binompdf(60, .99, 58)
\n" ); document.write( "P(at least two mistakes) = 1 - binomcdf(60, .01, 1).
\n" ); document.write( "P(> 2 mistakes) = binompdf(60, .01, 2).
\n" ); document.write( "b. what must be Clara's probability of getting any one note right
\n" ); document.write( "if she wants to have a 95% probability of getting all 60 notes right?
\n" ); document.write( " x^60 = .99
\n" ); document.write( " x = \"root%2860%2C.99%29\" = .9998 0r 99.98 % probability of correct \n" ); document.write( "
\n" );
