## How many numbers can you represent with 2 bytes?

65536If two bytes are used to represent numbers, that means that we define some function mapping the 65536 possible distinct values that those two bytes can take, to the numbers that these values represent..

## How do you unlock a 3 digit combination lock?

Unlock it With the CombinationTurn the lock until the numbers read right-side-up. … Roll the middle dial until the appropriate number lines up with the number to its left. … Pull the body of the lock away from the U-shaped metal ring without turning any of the dials.

## How many ways can you order 3 things?

6 waysFactorial Formula Therefore, the number of ways in which the 3 letters can be arranged, taken all a time, is 3! = 3*2*1 = 6 ways. Number of permutations of n things, taken r at a time, denoted by: Pr = n! / (n-r)!

## What does 5 choose 3 mean?

5C3 or 5 choose 3 refers to how many combinations are possible from 5 items, taken 3 at a time. What is a combination? Just the number of ways you can choose items from a list.

## How do you calculate all possible combinations?

Combinations are a way to calculate the total outcomes of an event where order of the outcomes does not matter. To calculate combinations, we will use the formula nCr = n! / r! * (n – r)!, where n represents the total number of items, and r represents the number of items being chosen at a time.

## How many combinations of 3 binary numbers are there?

There are actually eight three-digit binary numbers, since each position can get two values, hence 2×2×2=8. Your list misses 010. This is an example of the product rule: the number of possible pairs (a,b) constrained only under a∈A and b∈B (but no constraint on both elements at once) is |A|⋅|B|.

## What does 101 mean in binary?

When you say a binary number, pronounce each digit (example, the binary number “101” is spoken as “one zero one”, or sometimes “one-oh-one”). This way people don’t get confused with the decimal number. A single binary digit (like “0” or “1”) is called a “bit”. For example 11010 is five bits long.

## How do you write 13 in binary?

For example, if we write 10 in hexadecimal, do we mean the decimal number ten, or the binary number of two (1 + 0)….Hexadecimal Numbers.Decimal Number4-bit Binary NumberHexadecimal Number111011B121100C131101D141110E15 more rows

## What is nPr formula?

nPr(n, r) The number of possibilities for choosing an ordered set of r objects (a permutation) from a total of n objects. Definition: nPr(n,r) = n! / (n-r)! nCr(n, r)

## How many combinations are there for a 3 Number Lock?

2 Picking a Lock By comparison, this 3-dial lock (three wheels, each with digits 0-9) has 10 � 10 � 10 = 1, 000 possible combinations.
