- In an
In an ABCD square, n interior points are chosen on each side. Find the number of all triangles whose vertices X, Y, and Z lie at these points and on different sides of the square. - What is 20
What is the least number that should be added to 2497 so that the sum of the digits is divisible by 5, 6, and 10? - Three flocks
Flocks of birds pass by, and one bird on a tree asks them, how many of you? And they respond, we are so plenty. The second flock of birds again passes by and asks the bird on a tree, how many of you? The response is we are one-half (1/2) of the first floc - Seven segments display
Electronic devices sometimes use the type of digits below, where each digit uses some short stripes. For example, seven uses three small stripes. What is the largest three-digit number that you can make if you use twenty stripes? - Dice conditional probability
I roll a 7-wall dice. What is the conditional probability that three fell if an odd number fell? - Dice unit probability
We roll two dice. One is 6-walled, and the other is 8-walled. What is the probability that at least one unit will fall? - A bag 2
A bag contains seven green and eight red jellybeans. How many ways can five jellybeans be withdrawn from the bag so that the number of green ones withdrawn will be less than 4? - Three-digit number creation From the number 5,4,0,7,8, create three-digit numbers, so they do not repeat and solve the problem by calculation.
- How many 23
How many times should a dice be rolled to obtain a most likely number of 2 points on it to be equal to 32? - Apples
Three types of apples are mixed in a box. What is the smallest number of apples we have to take from the box so that there are certainly at least three apples of the same kind among them? (Explain your solution!) - Probability - dices We roll six dice. What is the probability that: a) a six falls twice b) six falls four times
- Railway descent permille
Calculate the permille descent of the railway line in the section of 7.2 km by 21.6 m. - Card selection ways
How many ways do we know to select three cards from a deck of seven cards so that there are two red and one green between them? - Number digit sum How many numbers are less than 200, the digit sum of which is 6?
- PIN code probability
When entering the PIN code, we used the digits 2, 3, 4, 5, and 7 only once. What is the probability that someone will guess our PIN code on the first try? - Table tablecloth material
The table top is 1.2 m long, 55 cm wide, and 35 mm thick. Calculate how many regular meters of a 1 m wide roll are needed for a tablecloth that extends 15 cm beyond the bottom edge of the table on all sides. - A biologist
A biologist knows that the average length of a leaf of a certain plant is 4 inches. The standard deviation of the population is 0.6 inches. A sample of 20 leaves of that type of plant given a new type of plant food had an average length of 4.2 inches. At - Group placement ways
I have eight groups. How could they place first, second, and third? - Observatory and aircraft
The aircraft flying towards the observatory was aimed at a distance of 5300 m at an elevation angle of 28º and after 9 seconds at a distance of 2400 m at an elevation angle of 50º. Calculate the distance the plane has flown in this time interval, its spee - Debt purchase gain
