Answer 1

Answer: 23/29 or 79.31%

Explanation:

Answer 2

79.31%

Explanation:

First we need to find the total number of students.

We do that summing all the four values in the table:

Total students = 2 + 18 + 3 + 6 = 29

Then, the students that play a sport or an instrument are all student but the ones that don't play both:

Students(sport or instrument) = 29 - 6 = 23

So the probability of a random student playing a sport or an instrument is 23/29 = 0.7931 = 79.31%
