Answer:
A. How many times the ad appear:
= 400 times
B. How many hits the website must have for thread to appear 1000 times with 0.05 probability that an ad appears when the website is loaded.
= 20,000 hits
Explanation:
A. The probability that an ad appears when a particular website is loaded = 0.2
When the website gets 2,000 hits a day, the ad appears
= 2,000 x 0.2
= 400 times
B. When the probability that an ad appears when the website is loaded is 0.05.
Therefore, the website must have 20,000 hits for thread to appear 1,000 times
= 1,000/0.05
= 20,000 times
The probability of an ad appearing when a website is loaded is the chance that the event happens (i.e. the ad appears) from the many events that can happen.
