¿cuál es la probabilidad de obtener tres perros?

¿cuál es la probabilidad de obtener 2 gatos?

¿Cuál s la probabilidad de obtener 1 perro?

¿Cuál es la probabilidad de obtener 2 perros?

¿Cuál es la probabilidad de obtener 3 gatos?

¿Cuál es la probabilidad de obtener 1 gato?

12.5%

25%

50%

25%

12.5%

50%

Step-by-step explanation:

In this case, each event has a probability of 1/2, because the coin only has two faces, dog or cat.

Therefore the probability will be the multiplication of the probability of each event.

What is the probability of getting three dogs?

(1/2) * (1/2) * (1/2) = 0.125 = 12.5%

What is the probability of getting 2 cats?

(1/2) * (1/2) = 0.25 = 25%

What is the probability of getting 1 dog?

(1/2) = 0.5 = 50%

What is the probability of getting 2 dogs?

(1/2) * (1/2) = 0.25 = 25%

What is the probability of getting 3 cats?

(1/2) * (1/2) * (1/2) = 0.125 = 12.5%

What is the probability of obtaining 1 cat?

(1/2) = 0.5 = 50%

the formula of a slope:

from a table we have

substitute:

the slope of f(x) is -1.

the graph of funcfion g(x) is a horizontal line. the slope of a horizontal line is equal 0. therefore the slope of g(x) is 0.

-1 < 0

a.

step-by-step explanation:

step 1 distribute 2 to every term in the parentheses

step 2 add 10 on both sides of the equal sign
