Intersection of two sets is the set of common elements between them.
Further Explanation:
Operations on sets are the actions that can be performed on/between sets.
Two most common operations are: Union and Intersection
Union is consists of the elements of both sets combined while intersection consists of the common elements of sets.
<u>Example:</u>
Let
![A = \{1,2,3,4,5\}\\B=\{2,3,4,6,7\}](https://tex.z-dn.net/?f=A%20%3D%20%5C%7B1%2C2%2C3%2C4%2C5%5C%7D%5C%5CB%3D%5C%7B2%2C3%2C4%2C6%2C7%5C%7D)
The intersection is denoted by ∩.
So,
A∩B = {1,2,3,4,5} ∩ {{2,3,4,6,7}
Intersection will give the elements which will be common in both sets.
So,
A∩B= {2,3,4}

P(X \ Y) = P(X ∩ Y)/P(Y)
P(X ∩ Y) = 80/1000 = 0.08
P(Y) = 580/1000 = 0.58
P(X \ Y) = 0.08/0.58 = 8/58 = 4/29
Answer:
see below
Step-by-step explanation:
y = a ( x-0)^2 + 5 sub in the point given to calculate 'a'
1 = a (4)^2 + 5
-4 = 16a
a = - 1/4
y = -1/4 x^2 + 5
Answer:
10
Step-by-step explanation:
Means back the numbers into multiples of several small numbers
Like:; 1. We take LCM of 40
Just break into multiples of small number
40= 2×2×2×5
2. We take LCM of 50
50= 5×5×2
So LCM for 100 is 2×2×5×5
after that see the pairs in the LCM like 2×2 or 3×3 or 4×4(same numbers)
Then write the the single number in place of two multipled numbers
Like:; 2×2 is written as 2 // 3×3 is written as 3
So we can write 100 into 2×2×5×5 and then after selecting pairs (2×2)×(5×5)
write pairs in single number 2×5
And so we get 2×5=10
So we find root of 100 that is 10
