Question

How many permutations of four different letters are there, chosen from the $26$ letters of the alphabet?

• A. $14950$
• B. $23751$
• C. $358800$
• D. $456976$

Answer 1

Answer: (C)

$358800$

Total number of letters $=26$

Number of letters to be selected $=4$

$\Rightarrow$ Number of ways of selecting $4$ot of $26$ ways

${=}^{26}{P}_4=26\times 25\times 24\times 23=650\times 24\times 23=14950\times 24=358800$

Therefore number of permutation possible $=358800$
