Answer: Our required probability is 47.3%.
Step-by-step explanation:
Since we have given that
Probability of schools or district in a country use digital content = 86% = 0.86
Probability of schools or district uses digital content as a part of their curriculum out of 86% = [tex]\dfrac{11}{20}[/tex]
So, Probability that a selected school or district uses digital content and uses it as a part of their curriculum is given by
[tex]\dfrac{86}{100}\times \dfrac{11}{20}\\\\=0.86\times 0.55\\\\=0.473\\\\=47.3\%[/tex]
Hence, our required probability is 47.3%.
The probability that a randomly selected school or district uses digital content and uses it as part of their curriculum is 47.3% and this can be determined by using the given data.
Given :
- According to a study, 86% of K-12 schools or districts in a country use digital content such as ebooks, audiobooks, and digital textbooks.
- Of these 86%, 11 out of 20 use digital content as part of their curriculum.
The probability that a randomly selected school or district uses digital content and uses it as part of their curriculum is given by:
[tex]=\dfrac{11}{20}\times \dfrac{86}{100}[/tex]
Now, multiply 11 by 86 and also multiply 20 by 100 in the above expression.
[tex]=\dfrac{11\times 86}{20\times 100}[/tex]
SImplify the above expression.
[tex]=\dfrac{946}{2000}[/tex]
= 0.473
So, the probability that a randomly selected school or district uses digital content and uses it as part of their curriculum is 47.3%.
