2/5 or 2 divided by 5. 2 pounds are divided up by 5 friends.
Answer:
A its like, getting a plate before you make a sandwich, you have to get a plate first, or else you can't start making your sandwich.
Step-by-step explanation:
you don't have to give brainliest, im just helping lol

White block(s) = 2
Red block(s) = 1
Purple block(s) = 3
Total = 2 +1 + 3 = 6 blocks
a) P(white) =
![\frac{2}{6} = \frac{1}{3}](https://tex.z-dn.net/?f=%20%5Cfrac%7B2%7D%7B6%7D%20%3D%20%5Cfrac%7B1%7D%7B3%7D%20)
P(red) =
![\frac{1}{6}](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B6%7D%20)
P(purple) =
![\frac{3}{6} = \frac{1}{2}](https://tex.z-dn.net/?f=%20%5Cfrac%7B3%7D%7B6%7D%20%3D%20%20%5Cfrac%7B1%7D%7B2%7D%20)
b)Not white block:
1 -
![\frac{1}{3}](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B3%7D%20)
OR
![\frac{2}{3}](https://tex.z-dn.net/?f=%20%5Cfrac%7B2%7D%7B3%7D%20)
Because, when they say no white blocks, we simply do not count them and add the rest to find that probability without white blocks.
c) The probability stays the same: lets say now we have
4 white blocks, 2 red, and 6 purple, total will be 12
P(white)=
![\frac{4}{12}](https://tex.z-dn.net/?f=%20%5Cfrac%7B4%7D%7B12%7D%20)
which is still
![\frac{1}{3}](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B3%7D%20)
d) We get two more blocks in the numerator: lets say we have 4 white blocks, 3 red, 5 purple (after adding 2 of each color), total will be 12
P(purple)=
![\frac{5}{12}](https://tex.z-dn.net/?f=%20%5Cfrac%7B5%7D%7B12%7D%20)
(im not quite sure if my explanation here helps you though)
e) 1 more of white and purple, 5 more of red
white = 3, purple = 4, red = 6, total = 12
(you can either add 2 to white or purple but make sure you add 5 of red)
P(red)=
![\frac{6}{12}](https://tex.z-dn.net/?f=%20%5Cfrac%7B6%7D%7B12%7D%20)

Answer:
you should count how many time two or more line touches each other
