In how many ways can 3 letters be mailed in 6 mailboxes if each letter must be mailed in a different box? If the letters are not
meriva

Answer:

Question 1: 120 ways

Question 2: 216 ways

Question 3: 1/36 = 0.278

Explanation:

<u>Question 1: In how many ways can 3 letters be mailed in 6 mailboxes if each letter must be mailed in a different box? </u>

The first letter may be mailed in any of the 6 mailboxes: 6

The second letter may be mailed in any of the other 5 mailboxes: 5

The third letter may be mailed in any of the other 4 mailboxes: 4

According to the fundamental counting principle, the total number of possible outcomes is the product of the possible outcomes for each event.

Thus, the number of ways 3 letters can be mailed in 6 mailboxes, if each letter must be mailed in a different box is 6 × 5 × 4 = 120.

<u>Question 2: If the letters are not necessarily mailed in different boxes, how many ways are there of posting them? </u>

Again, you must use the fundamental counting principle.

This time, since the letters are not necessarily mailed in different boxes, each one can be mailed in 6 boxes, and the total number of ways 3 letters can be mailed is:

  • 6 × 6 × 6 = 216.

<u>Question 3. If the letters are mailed at random, and not necessarily in different boxes, what is the probability that all the letters are put in the same mailbox?​</u>

<u></u>

The probability that all the letters are put in the same mailbox is:

  • number of favorable outcomes / number of total possible outcomes

  • number of favorable outcomes: 6

        This is: the three letters are mailed in the first mailbox, or the three letters in the second mailbox, or the three letters in the third mailbox, or the three letters in the fourth mailbox, or the three letters in the fifth mailbox, or the three letters in the sixth mailbox: 6.

  • number of total possible outcomes: 216 calculated in the question number 2.

  • probability = 6 / 216 = 1/36 = 0.278

uysha [10]

Answer:

Step-by-step explanation:

Unit rate = $32/(5 pounds) = $6.40/pound

[You can convert that to smaller units:

$6.40/pound × (1 pound)/(16 ounces) = $0.40/ounce]

:::::

Cost = (number of pounds) × $6.40/pound

:::::

12 pounds × $6.40/pound = $76.80

For every 144 light bulbs produced, 6 are defective. Find the number of defective light bulbs that could be expected out of 720.
Lelu [443]
You are going to get the rate of the detects.
6 detects ÷ 114 light bulbs = 1/19 detects per light bulb

If there are 720 light bulbs, then the number of detects will be
720 light bulbs * 1/19 detects per light bulb = 37. 89 ≈ 38 detects
