A clerk has 4 different letters that need to go in 4 different envelopes. What is the probability that all 4 letters are placed

Burka [1]

1/4 * 1/3 * 1/2 * 1/1 = 1/24 chance that all 4 letters are placed in the correct envelopes.

With the first envelope, there are 4 choices of letters, so the probability of picking the correct letter is 1/4.

With the second envelope, there are 3 remaining letters, so the probability of picking the correct letter is 1/3.

The same logic follows the the third and final letter.

Answer:

The answer to your question is: 83 + 6 $\sqrt{35}$

Step-by-step explanation:

This is a square of a binomial.

(2 $\sqrt{5}$ + 3 $\sqrt{7} )^{2}$

1.- Square of the first term

( 2 $\sqrt{5} )^{2}$ = 4(5) = 20

2.- Twice the product of the two terms

(2)(2 $\sqrt{5} )$ (3 $\sqrt{7} )$ = 6 $\sqrt{35}$

3.- Square of the second term

(3 $\sqrt{7)})^{2}$ = 9(7) = 63

4.- Write the solution

20 + 6 $\sqrt{35}$ + 63

83 + 6 $\sqrt{35}$
