How many different 10-letter permutations can be formed from 8 identical H's and two identical T's?
melamori03 [73]

Answer:

<h3>45 different permutations</h3>

Step-by-step explanation:

Given 10 letters with 8 identical H's and two identical T's, the number of different permutations will be expressed as;

= \dfrac{10!}{8!2!}

= \dfrac{10*9*8!}{8!*2!}\\ \\= \dfrac{10*9}{2*1}\\ \\= \dfrac{90}{2}\\ \\= 45

<em>Hence the number of different 10-letter permutations that can be formed from 8 identical H's and two identical T's is 45</em>
