If there are 512 relation from a set A = [1,2,3] to a set B, then find number of elements in B ​
kramer

<u>EXPLANATION</u><u>:</u>

Given set A = { 1,2,3}

n(A) = 3

Let the n(B) be n

Total number of relations from A to B = 2^(3×n) =2^3n

According to the given problem

Total relations are = 512

⇛2^3n = 512

⇛2^3n = 2⁹

If bases are equal then exponents must be equal

⇛3n = 9

⇛n = 9/3

⇛n = 3

<h3>So, Number of elements in the set B = 3</h3>

poizon [28]

Answer:

Step-by-step explanation:

Suppose :

62% own an HDTV

16% own a computer

Using the addition rule : suggests that (62% + 16%) = 78% either own an HDTV or a computer.

The reasoning is wrong because ; since it is possible to own both an HDTV and also own a computer at the same time, the outcome of the addition rule is wrong as both events are independent. If both event cannot occur at the same time (mutually exclusive event) , then, the addition rule may be applied,. But since both can occur independently and each family can own an HDTV while also owning a computer, then the addition rule is wrong for the scenario described.
