The Explanatory variable otherwise know as the independent variable in the study is the Ginkgo biloba administered to the students in doses of 250,500 and 1000 milligrams everyday for one month.
Total outcomes = 6*6 = 36
favourable outcomes = (1,3), (2,2), (3,1)
Probability = 3/36 = 1/12

The given equation-(3x + 5)^2 is not a perfect trinomial because it is not obtained through the multiplication of a binomial.
<h3>What is a perfect trinomial?</h3>
A perfect square trinomial is takes the algebraic expression form ax^2 +bx + c, where the square root of the first term and the third term is the equation to the second term.
Given that:
-(3x + 5)^2
Open brackets
= - (9x +30x + 55)
Multiply through by (-)
= -9x^2 - 30x - 55
Therefore, we can conclude that the given equation-(3x + 5)^2 is not a perfect trinomial because it is not obtained through the multiplication of a binomial. i.e. the multiplication of the square root of the first and the third term did not result in the 2nd term.
