Answer:
A box contains 5 green pencils and 7 yellow pencils.
Two pencils are chosen at random from the box without replacement.
=> There are two cases:
1st pick green & 2nd pick yellow: P = 5/12 x 7/11 = 0.265
1st pick yellow & 2nd pick green: P = 7/12 x 5/11 = 0.265
Add up both cases, the probability they are different colors:
P = 0.265 + 0.265 = 0. 53
Hope this helps!

Answer:
Mean = 8
Step-by-step explanation:
The mean is another way of describing the average. To find the mean, you need to (1) add all of the numbers together and (2) divide by the amount of numbers added.
(Step 1)
4 + 10 + 12 + 8 + 6
= 40
(Step 2)
4, 10, 12, 8, 6 -----> There are 5 numbers
40 / 5
= 8
Answer:
You should add 4 to both sides because that would make the left side a perfect square which is what you are intending to do when you complete the square.
