Suppose you select 2 letters at random from the word \"pacific\".
\n" ); document.write( "vowels: a,i,i
\n" ); document.write( "consonants: p,c,f,c
\n" ); document.write( "-----------\r
\n" ); document.write( "\n" ); document.write( "find each probability
\n" ); document.write( "P(2 vowels) = 3C2/7C2 = 3/21 = 1/7
\n" ); document.write( "--------------
\n" ); document.write( "P(2 consonants) = 4C2/7C2 = 6/21 = 2/7
\n" ); document.write( "--------------
\n" ); document.write( "P(1 vowel, 1 consonant) = 1 - [1/7 + 2/7] = 4/7
