Question 1159622
<br>
The number of ways to arrange the letters to begin with EXACTLY two O's is the total number of ways to arrange the letters beginning with AT LEAST 2 O's, minus the number of ways to arrange them starting with 3 O's.<br>
The number of ways to arrange the letters starting with AT LEAST 2 O's is the number of ways of arranging the letters TRNTO, which is {{{5!/2! = 120/2 = 60}}}<br>
The number of ways of arranging the letters starting with 3 O's is the number of ways of arranging the letters TRNT, which is {{{4!/2! = 24/2 = 12}}}.<br>
The number of ways of arranging the letters starting with EXACTLY 2 O's is 60-12 = 48.<br>
ANSWER: 48 ways to arrange the letters of TORONTO starting with exactly two O's.<br>
