Okay! Let's write out all the numbers:
1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
Now, let's bold (or you can circle them... or do really anything to them as long as they are standing out to you) the even numbers (remember all even numbers are divisible by 2)
1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
Now let's list all the ones we highlighted:
2
4
6
8
10
12
14
Count up how many numbers that is.
You should get 7.
So, our answer is 7 out of 15 numbers.
Or as a fraction:
7/15 is our answer.
Note: A probability is the number of chances something has to happen out of the total number of chances. So in this case the number of even numbers out of the total number of numbers. You can apply this to any probability problem. Hope this helps!

a³ + b³ + c³ + 3abc = ( a + b + c)(a² + b² + c² + ab + bc + ca)
if a + b + c = 0. then a³ + b³ + c³ = 3abc
here a + b + c = 15 + (-9) + (-6)
a + b + c = 15 - 15
a + b + c = 0
so a³ + b³ + c³ = 3abc
15³ + (-9)³ + (-6)³ = 3(15)(-9)(-6)
= 2430
so the answer is 2430
Answer:
<em>The probability that it would contain at least 6 letters is: </em><u><em>5/8</em></u>
<u><em></em></u>
Step-by-step explanation:
From the question given above,
We know that there are 8 planet that was given.
Mercury 7 letters
Venus 5 letters
Earth 5 letters
Mars 4 letters
Jupiter 7 letters
Saturn 6 letters
Uranus 6 letters
Neptune. 7 letters
Therefore,
P(at least 6 letters) + P( Less than 6 letters) = 1
P (at least 6 letters) + P (3 planet) = 1
P (at least 6 letters) + ( 3/8) = 1
P(at least 6 letters) = 1 - (3/8)
= 5/8
