klasskru [66]

Answer:

0.82

Step-by-step explanation:

Given:

A be the event that an Internet user posts photos taken by themselves.

B be the event that an Internet user posts photos taken by themselves.

P(A) = 0.47

P(A) = 0.28

P(A or B) = $P(A\cup B)$ = 0.52

To find:

Conditional probability that an Internet user posts photos given that they post videos.

P(A/B) = ?

Solution:

Formula to be used to find the required conditional probability:

$P(A/B) = \dfrac{P(A \cap B)}{P(B)}$

For this, $P(A \cap B)$ is required.

Formula

$P(A \cup B) = P(A) + P(B) - P(A \cap B)$

$0.52=0.47+0.28-P(A\cap B)\\\Rightarrow P(A\cap B)=0.23$

Now, the required conditional probability is:

$P(A/B) = \dfrac{P(A \cap B)}{P(B)}\\\Rightarrow P(A/B) = \dfrac{0.23}{0.28}\\\Rightarrow \bold{P(A/B)} = 0.82}$

So, the answer is 0.82.
