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.
