Question

Suppose that 43% of all students on campus wear glasses. If two students are chosen at random , what is the probability that both wear glasses

Answer 1

18.49%

Explanation:

Since the chance 1 student wears glasses is 43%, that means it is the same probability for all students.

When you have more than 1 student, it is equal the percentage to the power of how many students

43% = 0.43

There is 2 students

0.43^2 = 0.1849

0.1849 x 100 = 18.49%

Hope this helps!
