Question

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.

Answer 1

Answer: 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% = $\dfrac{5}{10}$

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

$\dfrac{80}{100}\times \dfrac{5}{10}\\\\=0.8\times 0.5\\\\=0.4\\\\=40\%$

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