Answer 1

The question requires calculating the expected number of graduating students out of a group of 22 to attend their graduation, given an 85% attendance rate. Using the percentage converted to a decimal, the expected number is approximately 19 students.

Step-by-step explanation:

The question revolves around the concept of probability in the context of graduating students attending their graduation ceremony. If we assume that 85 percent of graduating students typically attend their graduation, then for a group of 22 graduating students, we can expect about 85% of them to attend. The calculation would be as follows:

• First, convert the percentage to a decimal: 85% = 0.85.
• Now, calculate the expected number of students: 22 students * 0.85 = 18.7, rounded to 19 students.

This means that out of 22 students, we would expect approximately 19 students to attend the graduation ceremony.
