To get the answer for this, draw first a tree diagram.

1 x £1

1 x £0.50

1 x £0.20

1 x £0.10

1 x £0.05

1 x £0.02

1 x £0.01

= £1.88

so probability of taking out a 20p coin is 1/7 for the first attempt.

But if you have more than one attempt, still make a tree diagram so you can easily see the probabilities.

in this passage from chapter 6 of "animal farm", by george orwell, what the author is ridiculing in this passage is the frivolity of some rules.

clover, the mare, believes she remembers that the fourth commandment forbade sleeping in beds because it was something that humans did. snowball, napoleon, and the pigs are brain-workers who look after the welfare of the farm. they are the obvious leaders because they are smart, and so they are entitled to eat the best food and sleep in beds. it is squealer, who says these lines making the difference between sleeping with sheets, what humans do, and sleeping in beds, what pigs do. the unwillingness to question authority makes the oppressed to obey without thinking.

Hi, my name is maya gupta.i'm here at a bank robbery that happened a few minutes ago.a man named tryce ramder is suspected to be the robber.i am here with daniel cottle to describe what happened."it was terrifying. we all just heard the door break and turned around. some man just had a gun and told us to freeze and drop our phones. luckily we had cameras. continuing on, the man walked up to a worker, and said "give me the money or i'll shoot you." i did not believe what i heard. after a few minutes, we heard sirens, and the robber looked fearful, yet so angry. so he took out a bomb and threw it near us. i was in the military, so i know what to do, so i told everyone to move away atleast and duck down and cover their ears. i almost got affected, but some woman was able to grab me and put me down, and cover my ears. she got affected, she passed out, and was taken to the hospital. i am gonna visit her now to her and give her gifts for what she did." you daniel cottle, let's all hope this woman will be alright. i am maya gupta and we are signing off.
