There are 12 ways to select one sheet.
7 of them have numbers less than 8.
The probability of selecting one of those is 7/12 = 0.58333 = 58 and 1/3rd percent
the mass goes on top and the the atomic number on the bottom ie: 12/6 C
The atomic number of an atom, which represents the number of protons in the nucleus, is typically written at the bottom of the element's symbol on a Bohr diagram. The diagram also shows the arrangement of electrons in energy levels around the nucleus based on the atomic number.
An autosum formula calculates the total sum of a range of cells, while an average formula calculates the average value of a range of cells. The autosum function adds up the numbers in the selected range and can be applied to any numerical data, whereas the average function calculates the arithmetic mean of the numbers in the selected range.
Paired numbers refer to two numbers that go together in some way, such as even and odd numbers, prime numbers, or consecutive numbers. To find paired numbers, you need to identify the relationship between the numbers you are working with and determine how they are connected or paired. For example, in the case of even numbers, you would pair each even number with its corresponding odd number.
Subscripts represent the number of atoms of an element in a molecule. They are written as small numbers to the right of the element symbol in a chemical formula. They indicate the ratio of elements in a compound.
It depend how many negative numbers are written on the cube.
10
The probability of selecting a 17 (or any number for that matter) is 1/20 or .05 or 5%.
The event space comprises the numbers 10 to 99, 90 such numbers. The favourable events are 15, 21, 27, ... , 99. There are 15 such numbers. So the probability is 15/90 = 1/6
To find the probability of selecting a number from 20 to 30 that is divisible by 3, we first identify the numbers in that range: 21, 24, 27, and 30. There are four suitable candidates, so the probability of selecting one of them is 4 out of 11 (the total numbers from 20 to 30, inclusive). After replacing the selected number, we check which of these are divisible by 12. Among the numbers listed, only 24 is divisible by 12. Therefore, the probability of selecting a number divisible by 3 and then finding it divisible by 12 is 1 out of 11, which simplifies to approximately 0.0909 or 9.09%.
53 - 1 or 1 chance in 54 or 0.0185 or 1.85%
The probability is(the total number of numbers on the spinner minus 5)/(the total number of numbers on the spinner)Another way to express the same probability is1 - 5/(the total number of numbers on the spinner)
The probability is 1/b.
The probability is 0.
The probability of spinning the number 3, or any number, is 1/4 or 0.25 since there is 4 numbers total.
Number of possible ways to pull out one sheet = 8Number of ways to pull out a number less than 5 = 4 (1, 2, 3, or 4)Probability of success = 4/8 = 50%
On the basis that numbers are a continuous variable, the probability of any particular number (or pair) is 0.
