4. Elena va a una fiesta pero no sabe que ponerse, así que lanza un moneda y un dado al

taurus [48]

Answer:

<u>1/4</u>

Explanation:

Hola. Puesto que tu pregunta está en español, te responderé en el mismo lenguage.

Estas son las posibilidades dadas por la combinación moneda/dado

Número de combinaciones

Moneda: prenda

Cara: vestido 1 de 2: 1/2

Sello: falda 1 de 2: 1/2

Dado: color

Par: negro 3 de 6: 3/6

Impar: café 3 de 6: 3/6

En total son 2 × 6 resultados: 12 (incluye resultados repetidos, no son todos diferentes entre sí)

¿Cuántas combinaciones tienen vestido y color negro?

P(Vestido∩negro) = ?

Es decir: moneda = cara y dado = par

Son 1 × 3 = 3.

Por tanto, la probabilidad de vestido negro es:

3 de 12 = 3/12 = 1/4 ← respuesta

Hay otras formas de resolverlo. Por ejemplo;

Como los resultados de lanzar la moneda y el dado son independientes:

P(Vestido∩negro) = P(Vestido) × P(Negro)
P(Vestido) = 1/2
P(Negro) = 3/6 = 1/2

P(Vestido) × P(Negro) = 1/2 × 1/2 = 1/4 ← mismo resultado

Answer:

p>-3 open circle going to the right

$m\leq -4$ closed circle going to the left

n<5 open circle going to the left

$h\geq 2$ closed circle going to the right

1>x open circle going to the left

-1=d just a closed circle

Step-by-step explanation:

Before I answer these here are some good notes

If the inequality sign is < or > then the circle is going to be open

If the inequality sign is $\leq or\geq$ then the circle is going to be closed

If the inequality sign is facing the variable (ex: x>3) then the line is going to be going to the right

If the inequality sign is facing the constant (ex: x<3) then the line is going to be going to the left

p>-3 open circle going to the right

$m\leq -4$ closed circle going to the left

n<5 open circle going to the left

$h\geq 2$ closed circle going to the right

1>x open circle going to the left

-1=d just a closed circle
