- Question knowledge probability
You will learn 50% of the 30 questions. If I get 4 questions, I'll know 3. - Heptagon triangle probability
We randomly select three different points from the vertices of a regular heptagon and connect them with line segments. The probability that the resulting triangle will be isosceles is equal to: (A) 1/3 (B) 2/5 (C) 3/5 (D) 4/7 - Consecutively numbers
How many ways are there to arrange the numbers 3, 2, 15, 8, and 6 so that the even numbers are arranged in ascending order (not necessarily consecutively)? - Crocodile length parts
Pampalini, an animal hunter, told a stranger how he caught a huge crocodile. He claimed that his head was as long as half his tail, and his body was as long as three and a half heads. How long was the crocodile if you know its tail was 4 meters? - Dice even probability
We roll the dice three times. Calculate the probability of getting an even number on the first, second, or third toss. - Cube tower ways
How many ways can a tower of five yellow and four blue cubes be built so that each yellow cube is adjacent to at least one other yellow cube? Yellow cubes are indistinguishable, and so are blue cubes. - Aja book pages
Little Aja planned to read the book, which has 120 pages, for 4 days. On the first day, she read a quarter of the whole book; on the second day, she had training and therefore only read two-fifteenths of the book; on the third day, she read seven-twentiet - Five-digit digit probability What is the probability that each digit is different in a five-digit number?
- Petr notebook price

Helen has 30% fewer books in her library than Philip but 40% more than Ivan. Philip has 250 books. How many books does Ivan have? - Potter figurine clay
How many figurines can a potter make from 133 1/3 kg of clay if he needs 4/15 kg of clay to make one and 1/20 of the material is wasted during production? - Number sum product
Calculate the difference between the sum and product of the numbers -7 and -2. - Percentage - fence
We are painting a wooden fence. On the first day, we painted one-half of the fence. The next day, we painted half of the remaining part. On the third day, again, half of the remaining part. After the third painting, we had 12.5 meters of unpainted fence l - Operation asterisk pairs
The * (asterisk) operation assigning one number to two pairs of numbers is introduced as follows: (a, b)*(c, d) = ac+bd We know that: (x,2)*(-1, v) = -1 and (2,-1)*(u, v)=5 and (u, v)*(1,1)=-2 What is (1,2)*(x, y) equal to if y=3? - Three fractions times
Eight thirds×nine quarters×twelve fifths - Friends money division
The three friends divided the money earned as follows: Tony got 2/5, Charles 2/9, and Jirko took the rest of CZK 102. How much did each of them earn? - Meeting handshake count

- Three cartridges - shooting
A shooter has three cartridges. He decided that he would shoot at the target until he hits for the first time. The probability of a hit at each shot is 0.6. The random variable X gives the number of cartridges fired. a) Write the probability distribution - Equal number multiplication When I multiply two equal natural numbers, I get the same result as when I add them together. Which ones are they?
