Answer:

\frac{6}{13} > \frac{4}{13}, o que implica que esta afirmativa é incorreta.

Step-by-step explanation:

Uma probabilidade é dada pelo número de resultados desejados dividido pelo número total de resultados.

Probabilidade de sair um cartão contendo um quadrado:

4 com quadrados

6 + 4 + 3 = 13 total

4/13 de probabilidade de sair um cartão contendo um quadrado

Probabilidade de sair um cartão contendo um triângulo:

6 com triângulos

13 total

6/13 de probabilidade de sair um cartão contendo um triângulo

\frac{6}{13} > \frac{4}{13}, o que implica que esta afirmativa é incorreta.

Amiraneli [1.4K]

Answer:

2 gallons

Step-by-step explanation:

So say we make everything into cups. We know there is 4 cups in a quart and 2 cups in a pint. So if we do the math you are really adding

4 cups + 4 cups + 8 cups + 16 cups

So that  would be 32 cups.

We also know there is 16 cups in a gallon. Since we know that then we can do

32 cups ÷ 16 cups

That would be 2 gallons!

Hope this helps!
