    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.
