To find the solutions to this equation, we can apply the quadratic formula. This quadratic formula solves equations of the form ax^2 + bx + c = 0
                   x = [ -b ± √(b^2 - 4ac) ] / (2a)
                   x = [ -5 ± √((5)^2 - 4(-11)(-3)) ] / ( 2(-11) )
                   x = [-5 ± √(25 - (132) ) ] / ( -22 )
                   x = [-5 ± √(-107) ] / ( -22)
Since we conclude that √-107 is nonreal, the answer to this question is that there are no real solutions.

Answer:

<em>Probability ⇒ 3 / 22</em>

Step-by-step explanation:

<em>~ Let us use this Venn Diagram to our benefit ~</em>

If 60 students are known to participate in both drama and sports, with 85 student in the drama club, and 200 in the sports teams;

Total Drama students ⇒ 85 students,

Drama students that are not in the sports teams ⇒ 85 - 60 = 25 students,

Total Sports Team students ⇒ 200 students,

Sports people not in Drama ⇒ 200 - 60 ⇒ 140 students

Now if there are a total of 330 students, we can find the students in neither club through such;

Total students in Drama and Sports ⇒ 85 + 200 = 285 students,

Students in Neither Drama nor Sports ⇒ 330 - 285 = 45 students,

<em>Students in Neither Drama nor Sports ⇒ 45 students</em>

This would mean the probability a students is neither in Drama nor Sports, is;

<em>Probability ⇒ 45 / 330 = 3 / 22</em>
