Jeanie is a bit forgetful, and if she doesn’t make a “to do” list, the probability that she forgets something she is supposed to do is 0.1. Tomorrow she intends to run three errands, and she fails to write them on her list. What is the probability that Jeanie forgets all three errands?

What is the probability that Jeanie remembers the first errand but not the second or third?

the direct variation says that:

then the equation is of the form is given by:

            where k is the constant variation.

from the given table:

consider any value of x and m(x)=y

x = 2 and m(x)=y = 3

substitute these value in [1]; we have;

divide both sides by 2 we get;

⇒

check:

put x = -1 and m(x) = -1.5

substitute in the equation:

-1.5 = -1.5                   true

therefore, the function m(x) represents a direct variation
