According to a study, 80% of k-12 schools or districts in a country use digital content such as ebooks, audio books, and digital textbooks. of these 80%, 5 out of 10 use digital content as part of their curriculum. find the probability that a randomly selected school or district uses digital content and uses it as part of their curriculum.

There is a probability of 40% of getting a school or district uses digital content and uses it as part of their curriculum.

Step-by-step explanation:

Since we have given that

Probability that schools or districts in a country use digital content = 80%

Probability that schools uses digital content as a part of their curriculum out of 80% =

So, the probability that a selected school or district uses digital content and uses it as  a part of their curriculum is given by

Hence, there is a probability of 40% of getting a school or district uses digital content and uses it as part of their curriculum.
