What is the meaning of "classical probability problem"?

The object of classical probability is limited to the case that all the possible results of random test are finite, that is, the basic space is composed of finite elements or basic events, the number of which is n, and the probability of each basic event is the same. If event a contains M basic events, the probability of event a is defined as P (a)

What are the methods for classical probability and geometric probability

If it is in senior high school, the topic of classical probability can almost be counted out, that is, P = target number / total number. Generally, the method of classical probability is used in the problem of discrete number
The geometric probability is usually uncountable, that is to say, it is generally to consider the case of continuous or whole piece, where p = the area / total area of the target area. Generally, in continuous data, the geometric probability is selected

What is the ancient meaning of geometry?

The sun rises from the southeast and shines on my Qin family's building. There is a beautiful girl in the Qin family. Her name is Luofu. Luofu is good at raising silkworms and growing mulberry. She often goes to the south corner of the city to pick mulberry leaves. The basket is tied with green ribbon, and the handle is made of cinnamon twigs

How to calculate velocity with acceleration time diagram
If the problem and known mass, find a moment speed?! thank you!

The area under the A-T curve is the velocity

3x + 3 / 2-2 = 3x-2 / 10-2x + 3 / 5, where 3x + 1 / 2 is 3x + 1 is the denominator, and so are 3x-2 and 2x + 3
How to calculate x = 7 / 16

(3x+3)/2-2=(3x-2)/10-(2x+3)/5
Multiply both sides of the equation by 10
5（3x+3)-2*10=3x-2-2(2x-3)
15x+15-20=3x-2-4x+6
15x+x=4+5
16x=9
x=9/16

What is the circumference of a rectangle made up of five small squares with an area of 3 square decimeters?
Third grade questions

The area of the square is: S = a * a = 3, then the side length of the square is a = root 3 decimeters
A rectangle made up of five squares, its perimeter L = 2 (5a + a) = 12a, where a = root sign is substituted, l = 12a = 12 root sign is 3 decimeters
Is this the third grade topic? It's too difficult!

There is a 50 Hz, 8-stage step motor with rated slip of 4%. What is the rated speed? How to calculate?

The synchronous speed of 8-pole motor is 50 * 60 / 4 = 750r / min
Rated speed = (1-0.04) * 750 = 720r / min

The equation 3 (AX-2) - (x + 1) = 2 (1 / 2 + x)
(1) Is there a unique solution? (2) no solution?

If we remove the brackets, we get 3ax-6-x-1 = 1 + 2x,
(3a-3) x = 8
(1) When 3a-3 ≠ 0, that is, a ≠ 1, the equation has a unique solution
(2) When 3a-3 = 0, i.e. a = 1, the equation has no solution

A rectangular sheet of iron with a width of 16 cm is cut out at its four corners, and the square with a side length of 4 cm is welded into a cuboid box without cover. If the volume of the box is 768 cubic cm, what is the original area of the sheet of iron?

The length of the box: 768 ^ [4 × (16-4 × 2)], = 768 ^ (4 × 8), = 768 ^ 32, = 24 (CM), the length of the original sheet iron: 24 + 4 × 2, = 24 + 8, = 32 (CM); the original area of the sheet iron: 32 × 16 = 512 (CM); a: the original area of this sheet iron is 512 cm

The formula for the volume of a cube in letters is______ The surface area formula is______ ．

The volume formula of a cube expressed by letters is v = A3, and the surface area formula is s = A2 × 6; therefore, the answer is v = A3, A2 × 6
