A bag contains 12 disks 7 red 3 blue 2 yellow two disks are taken from the bag at random without replacement work out the probability that the two disks are the same colour?
To find the probability that the two disks drawn are the same color, we first calculate the total ways to choose 2 disks from 12, which is ( \binom{12}{2} = 66 ). Then, we find the favorable outcomes: choosing 2 red disks ( \binom{7}{2} = 21 ), 2 blue disks ( \binom{3}{2} = 3 ), and 2 yellow disks ( \binom{2}{2} = 1 ). Adding these gives ( 21 + 3 + 1 = 25 ) favorable outcomes. Therefore, the probability is ( \frac{25}{66} ).
What is the least number of moves in the Tower of Hanoi puzzle with only 5 disks?
To move n disks, you need 2n-1moves. In this case, 31.
Least number of moves in the Tower of Hanoi puzzle with 5 disks?
The least number of moves required to solve the Tower of Hanoi puzzle with 5 disks is calculated using the formula (2^n - 1), where (n) is the number of disks. For 5 disks, this results in (2^5 - 1 = 32 - 1 = 31) moves. Therefore, the minimum number of moves needed is 31.
What are the diameters of the disks?
The diameters of the disks can vary widely depending on their intended use. For example, standard compact discs (CDs) have a diameter of 12 cm, while DVDs are also typically 12 cm. Hard drive disks can range from 2.5 inches (about 6.35 cm) for laptop drives to 3.5 inches (about 8.89 cm) for desktop drives. Other specialized disks, like those used in certain scientific applications, may have different dimensions.

What are floppy disks divided into?

How many number of tracks and sectors in hard disks?

What is a disk cluster?
A disk cluster is a location on a disk's surface that stores data. Most disks are divided into platters/cylinders, tracks, and sectors, and sectors are grouped into clusters when formatted with a file system.
What do formatted disks have that the system software uses to reference data locations?
Tracks and sectors
Can you give examples of a sentence with the word sector in it?
Hard disks are organized into sectors, tracks, and cylinders.
What is the Ms-DOS Structure?
Disks are always divided up into tracks and sectors, as shown in figure. To access any particular block of data, the program first moves to the correct track, then has you wait while the spinning disk moves the correct sector under the head.
How many floppy disc equal a 4gb flash drive?
You would need 729 floppy disks to hold 1GB of data. This is because:1 gigabyte is equal to 1,073,741,824 bytes1 floppy disk can hold 1,474,560 bytesSo floppy disks per gigabyte is equal to 1,073,741,824 divided by 1,474,560, which is 728.18 disks. This means you would need 729 disks to hold the full 1GB.
Can you remove burned data on disks?
Not usually. When CD, DVD, Blu-Ray, etc. Recordables are burnt, the data is usually fixed and cannot be added or removed. However, there are special disks called re-writable disks (RW) and the data can be removed and rewritten several times.
