Answer 1

Answer:

26.95%

Step-by-step explanation:

The computation of the probability that randomly selected is shown below:

Since 77% school or district use digital content

And, of these 77%, 7 out of 20 use the digital content as the curriculum part

So based on the above information

The probability is

= 77% × 7 ÷ 20

= 26.95%

Hence, the probability is 26.95%
