Example:
Assume you published a video on youtube 30 days before.
Your video got 300 views and 60 likes.
What is the probability of getting four likes tomorrow?
Solution:
Getting a view is an independent event.
Viewing the video is an experiment in our example.
Probability he click a like button = 60 / 300 = 0.2
Each experiment will result in two actions. Press the like button or no.
P(4 likes in one day) =?
300 views in 30 days. So ten views in one day.
Now, we got n = 10, p = 0.2, and x = 4.
P(X = 4) = 10C4 (0.2)^4 (0.8)^6
P(X = 4) = 0.08808
