The probability of randomly selecting a tree or a flower is 8/15.
<h3>What is the probability?</h3>
Probability determines the chances that an event would happen. The probability the event occurs is 1 and the probability that the event does not occur is 0.
The probability of randomly selecting a tree or a flower = (number of trees / total number of flash cards) + (number of flowers / total number of flash cards)
8/30 + 8/30 = 16/30 = 8/15

The value of (f· g)(x) from the given functions is
.
The given functions are f(x)=x³+x+1 and g(x)=-x.
<h3>What is the function?</h3>
Functions are the fundamental part of the calculus in mathematics. The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x.
Here,
(f·g)(x)= f(x) × g(x)
= (x³+x+1) × (-x)
= 
(g·f)(x)= g(x) × f(x)
= (-x) × (x³+x+1)
= 
Therefore, the value of (f· g)(x) from the given functions is
.
