A stack of 30 science flashcards includes a review card for each of the following: 10 insects, 8 trees, 8 flowers, and 4 birds.
Gnom [1K]

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

If f(x)=x³+x+1 and g(x)=-x, find (f°g)(x) and (g°f)(x).<br> (f°g)(x)=
andreev551 [17]

The value of (f· g)(x) from the given functions is -x^4-x^2-x.

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)

= -x^4-x^2-x

(g·f)(x)= g(x) × f(x)

= (-x) × (x³+x+1)

= -x^4-x^2-x

Therefore, the value of (f· g)(x) from the given functions is -x^4-x^2-x.
