دي معقولة شوية In Mrs. Melanie's class are twenty-six children. None of the children was born on February 29th.
The Question: What is the probability that at least two children have their birthdays on the same day?
لكن دي محتاجة وقت اكتر و مجهود
There is a unique number of ten ciphers, for which the following holds: all ciphers from 0 up to 9 occur exactly once in the number; the first cipher is divisible by 1; the number formed by the first two ciphers is divisible by 2; the number formed by the first three ciphers is divisible by 3; the number formed by the first four ciphers is divisible by 4; the number formed by the first five ciphers is divisible by 5; the number formed by the first six ciphers is divisible by 6; the number formed by the first seven ciphers is divisible by 7; the number formed by the first eight ciphers is divisible by 8; the number formed by the first nine ciphers is divisible by 9; the number formed by the ten ciphers is divisible by 10. The Question: Which number is this?
ودي كمان ... William lives in a street with house-numbers 8 up to 100. Lisa wants to know at which number William lives.
She asks him: "Is your number larger than 50?" William answers, but lies. Upon this, Lisa asks: "Is your number a multiple of 4?" William answers, but lies again. Then Lisa asks: "Is your number a square?" William answers truthfully. Upon this, Lisa says: "I know your number if you tell me whether the first digit is a 3." William answers, but now we don't know whether he lies or speaks the truth.
Thereupon, Lisa says at which number she thinks William lives, but (of course) she is wrong.
The Question: What is Williams real house-number?
