Answer:

7 bolas

Step-by-step explanation:

Aquí, queremos saber el número de bolas que se deben sacar para estar seguros de haber extraído al menos dos bolas del mismo color.

De la pregunta, hay 6 tipos y 5 tipos de bolas diferentes. Así que en caso de que saquemos 6 veces y tuviéramos las mismas bolas, estaríamos seguros de que en el séptimo sorteo estaremos cogiendo una bola de otro color ya que hemos agotado el número de bolas del primer tipo y nos queda solo con las bolas del segundo tipo.

There are n apples in a box; this is 3/7 of all the fruits in it. How many fruits are there in the box? (n=21)
Morgarella [4.7K]

Answer:

49

Step-by-step explanation:

n is 3/7 of total fruit

n=21 apples

Here they are just telling us that the apples make up a total of 3/7 percent of the total fruit in the box. So to find the total amount of fruit from this information we just simply take the n number of apples and divide that by the percent that it represents. So basically just this;

n=21 and (n)/(3/7)=total fruit

(21)/(3/7)=21*7/3=147/3=49 total fruit and 21apples make up (3/7)% of the total fruit in the box.

Hope this helped some. Any questions please feel free to ask. Thanks!
