Answer:
To make sure you understand it and to be sure the facts are clear.
Explanation:
If repetition is not allowed in the 5 digit pin, then number of possible pins = 10C5 = 252
P(guessing it right in the first attempt) = 1/252
P(guessing it right in the second attempt) = 251/252 * 1/251 = 1/252
P(guessing it right in the second attempt) = 251/252 * 250/251 * 1/250 = 1/252
P(of guessing it right in 3 attempts .with different pin each time) = 1/252 + 1/252 + 1/252 = 3/252 = 1/84 = 0.0119
If repetition is allowed in the 5 digit pin, then number of possible pins = 10^5 = 100000
P(guessing it right in the first attempt) = 1/100000
P(guessing it right in the second attempt) = 99999/100000 * 1/99999 = 1/100000
P(guessing it right in the second attempt) = 99999/100000 * 99998/99999 * 1/99998 = 1/100000
P(of guessing it right in 3 attempts .with different pin each time) = 1/100000 + 1/100000 + 1/100000 = 3/100000 = 0.00003
<span>The story of “The Devil and Tom Walker” is similar to an older tale called Faust.
In Faust, the protagonist sells his soul to the Devil in order to get all the knowledge in the world. He wanted to know everything, and be the smartest person ever, which is why he decided to sign a contract with the Devil himself in return for this knowledge. A similar thing happened in "The Devil and Tom Walker."
