What is the probabilitly of rolling a 4 on a 10-sided dice?
The probability is (0.1) times (the number of faces with '4' marked on them).
If referring to a set of individual integers, the mode would be the integer which occurs most often.
What is the relevance of probability and statistics in the field of information technology?
In the field of IT you are dealing with probabilities all day long. How long will the hardware last, how can you keep the signal for the network strong all over the building, how will adding a new group of computers impact the network, or heaven forbid your network come under attack and you need to keep damage to a minimum while fending off the attack. IT professionals think in probabilities. They're always running scenarios through their heads to come up with and fix problems before they occur.
How many 5 digit numbers exist such that the product of their digits is 400?
120.
First factorising 400 gives: 400 = 24 x 52
So the 5 digit number must contain two 5s and the other three digits must multiply together to give 16, namely: 1, 2 & 8; 1, 4 & 4 or 2, 2 & 4
When selecting from 5 digits, they can be arranged in 5! = 5 x 4 x 3 x 2 x 1 = 120 different ways. However, some of the digits are indistinguishable (eg the two 5s can swap places and the number is the same), so when this happens, the total number of ways needs to be divided by the number of ways the indistinguishable numbers can be arranged.
Two digits can be arranged in 2! = 2 x 1 = 2 ways.
So the 5 digit number can contain:
- 1, 2, 8, 5, 5
120 ÷ 2 = 60
possible numbers here
- 1, 4, 4, 5, 5
(120 ÷ 2) ÷ 2 = 30
possible numbers here
- 2, 2, 4, 5 ,5
(120 ÷ 2) ÷ 2 = 30
possible numbers here
So the total number of possible numbers is 60 + 30 + 30 = 120.
To find the HCF of two numbers you first have to write them as their prime factors:
14 = 2x7
42 = 2x3x7
The next step is to identify any common prime factors. In this case both numbers have a 2 and a 7 as prime factors. Multiply these together and you get:
2x7 = 14
Thus the HCF of 14 and 42 is 14.
What is mean in data handling?
the "mean" is the "average" you're used to, where you add up all the numbers and then divide by the total number of numbers
