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.

3. If a snail moves
Mila [183]
Hi there!

We know that the snail lives 1 x 1/2 feet in 3 x 3/4 hours. First you have to simplify or solve the expressions. 1 x 1/2 is equal to 1/2 and 3 x 3/4 is 9/4 or 2.25 in decimal form.

You need to divide 2.25 by 1/2 or 0.5 which is 4.5.

So the snail moves 4.5 or 9/2 feet per hour.

Hope this helps !
