The answer is 30% because if there is a 70% chance then minus 70% from 100% you get 30%

30% because 100-70=30 just add a percent sign after the number.

Answer:

9) x = gy/c, 11) a = np/m

Step-by-step explanation:

9) g = xc/y

g*y/c = xc/y *y/c

gy/c = x

11) am = np

am/m = np/m

a = np/m

The number of permutations of the problem is

This = 24
Outfit = 360

<u>。。。。。。。。。。。。。。。。。。。。。。。。。。。。。</u>

<u> $\:$ </u>

<h2>Combination</h2>

$\:$

Combinations are the number of ways to choose members from a certain number, namely from members of a set, combinations can also be interpreted as many ways to make subsets, namely with a certain number of members, namely from members of a set, if a set has n members then the selection of r members, and the combination of n is where r is less than n.

$\:$

<h3>The Formula : </h3>

$\:$

<h2> $\frac {n!}{k! (n-k)!}$ </h2>

$\:$

<h2>Permutation</h2>

$\:$

Permutations are a way to determine the number of arrangements that occur by paying attention to the order. So in permutations, position/order is very important, namely AB is considered different from BA (AB ≠ BA). Permutation formula

$\:$

<h3>The Formula :</h3>

$\:$

$\frac {n!}{k!}$ (With Double Elements)

n! (Without Double Elements)

$\:$

<h2>Factorial</h2>

$\:$

The factorial of a natural number is the successive multiplication of a natural number that begins with the number one and arrives at the natural number, the factorial is used in calculating combinations, probabilities, and permutations.

$\:$

<h3>For example</h3>

$\:$

》2! = 1 × 2
》3! = 1 x 2 x 3
》4! = 1 x 2 x 3 x 4
》5! = 1 x 2 x 3 x 4 x 5
》6! = 1 × 2 × 3 × 4 × 5 × 6
》7! = 1 × 2 × 3 × 4 × 5 × 6 × 7
》8! = 1 × 2 × 3 × 4 × 5 × 6 × 7 × 8
》9! = 1 × 2 × 3 × 4 × 5 × 6 × 7 × 8 × 9
》10! = 1 × 2 × 3 × 4 × 5 × 6 × 7 × 8 × 9 × 10

$\:$

The following is an example of a factorial that does not involve mixed arithmetic operations, so if you want to add it up we just need to calculate it like a normal number, a factorial number that only multiplies the difference between a factorial number that is added up by addition, subtraction, multiplication, division, for example see below.

$\:$

6! x2! - 3! : 4!

$\:$

The example above is a mixed arithmetic operation that contains multiplication, subtraction, and division. Remember that in mixed arithmetic operations, multiplication/division must be completed before addition/subtraction.

<h3>The Formula : </h3>

$\:$

n! (Combined Multiplication)

<h2>Place Filling Rules</h2>

$\:$

The Place Fill Rule is a method or method that can be used to determine the number of ways an object occupies its place. The filling slots rule is a method of calculating how many possible ways there are in an experiment or event. If a first event can be done in m different ways and the second event can be done in a different way and so on until the last event in k.

<h3>The formula</h3>

$\:$

n1 × n2 × n3 × ... × nr

<h2><u>Question</u></h2>

Find the number of permutations of letters of the word

- this

- outfit

$\:$

<h2><u>Answer</u></h2>

"Number One"

=》This = Four Letters ( 4! )

P = 4!

P = 1 × 2 × 3 × 4

P = 2 × 3 × 4

P = 6 × 4

P = 24

==========

"Number Two"

=》Outfit = Six Letters ( 6! )

=》Outfit = Two Letters The Same ( "T" ) = 2!

P = $\frac {1×2×3×4×5×6}{2×1}$

P = $\frac {2×3×4×5×6}{2}$

P = $\frac {6×4×5×6}{2}$

P = $\frac {24×5×6}{2}$

P = $\frac {120×6}{2}$

P = $\frac {720}{2}$

P = 360

$\:$

<h2><u>Conclusion</u></h2>

So, the number of permutations of the problem is

This = 24
Outfit = 360
