a.)At most one head means one head or no head.
\n" ); document.write( "4 outcomes:HTT THT TTH TTT
\n" ); document.write( "P(at most 1 H)=4/8=1/2
\n" ); document.write( "
\n" ); document.write( "b.)At most two tails means two tails, one tail or no tail. Or simpler, not three tails.
\n" ); document.write( "Since only TTT has 3 tails, then all the rest have at most 2 tails.
\n" ); document.write( "P(at most 2 T)=7/8
\n" ); document.write( "
\n" );
