Answer:

\dfrac{2}{91}

Step-by-step explanation:

There are 15 toppings: 5 toppings are meat and 10 toppings are vegetable.

You and two friends form a group of 3 people.

Find the number of choices 3 different meat toppings:

C^5_3=\dfrac{5!}{3!(5-3)!}=\dfrac{5!}{3!\cdot 2!}=\dfrac{3!\cdot 4\cdot 5}{3!\cdot 2}=10

Find the number of choices 3 different toppings:

C^{15}_3=\dfrac{15!}{3!(15-3)!}=\dfrac{15!}{3!\cdot 12!}=\dfrac{12!\cdot 13\cdot 14\cdot 15}{12!\cdot 2\cdot 3}=13\cdot 7\cdot 5=455

Hence, he probability that your group orders only meat toppings is

\dfrac{10}{455}=\dfrac{2}{91}

MArishka [77]

Respuesta:

A.) BA = 12 m

Explicación paso a paso:

Usando triángulos similares:

BA / AC = DE / EC

BA = x; AC = 20; DE = 3; EC = 5

POR ESO ; TENEMOS :

x / 20 = 3/5

Multiplicar en cruz:

5 * x = 20 * 3

5 veces = 60

5x / 5 = 60/5

x = 12
