Answer:-12x+33-8w
Step-by-step explanation:
A binomial probability density function should be used to represent the probability
<h3>How to determine the type of
probability density?</h3>
The given parameters are:
- Proportion that plays sport, p = 32%
- Number of students selected, p = 50
- The probability, P = (x ≤ 15)
The proportion that plays sport indicates that
68% of the students do not play sport
So, we have two events, which are
- Play sport
- Do not play sport
When there are two possible events, then the binomial probability density function should be used

Answer:
0.82
Step-by-step explanation:
Given:
<em>A</em> be the event that an Internet user posts photos taken by themselves.
<em>B</em> be the event that an Internet user posts photos taken by themselves.
P(A) = 0.47
P(A) = 0.28
P(A or B) =
= 0.52
To find:
Conditional probability that an Internet user posts photos given that they post videos.
OR
P(A/B) = ?
Solution:
<em>Formula </em>to be used to find the required conditional probability:

For this,
is required.
<em>Formula</em>


Now, the required conditional probability is:

So, the answer is <em>0.82</em>.
6,137 i believe is the correct answer.
