Help me please

Step-by-step explanation:

g(f(x))  means that we find an equation where f is a function of g. so we substitute f(x) in all x values for g, so therefore

then we simplify this equation and solve for g(f(x)).

we have multiplied by 3 the equation of f(x)

we then add or subtract like terms which are those terms that have the same variables.

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%

the probability that a bird is green (.30) is true
