Calcular la probobilidad. \( A= \) que la suma de los puntos sea 5 \( B= \) De que ambos numeros seon pares The probability that Esther wins a competition is 0.003 Convert this probability to a percentage \[ (\%) \text {. } \] ¿Cuál es la probabilidad que al lanzar dos dados, obtenga un puntaje múltiplo de 5 ? Question \( 7 \mid 4 \) marks] The job of a chef culinary artist involves more than simply cooking food; it is about crafting an entire sensory experience where the five senses in human perception is in use. If a chef culinary artist's most used sense is Sight, the probability of that chef's clients' dining experience being of high quality is \( 71 \% \). If a chef culinary artist's most used sense is Hearing, the probability of the dining experience being of high quality is 23\%. If the most used sense is Smell, the probability of the dining experience being of high quality is \( 43 \% \); however, if the most used sense is Taste, the probability of the high-quality dining experience is \( 89 \% \). If the most used sense of the chef culinary artist is Touch, the likelihood of the high-quality dining experience is only \( 17 \% \). Of a batch of chef culinary artists, a survey revealed that the most used sense was Sight for \( 17 \% \) of them, Hearing for \( 2 \% \) of them, Smell for \( 31 \% \), Taste for \( 39 \% \), and Touch for \( 11 \% \) of them. i. A chef culinary artist is selected from the batch to manage the dining experience of some clients. Given that the chef's clients' dining experience is of high quality, what is the probability that the most used sense of the chef culinary artist was Sight or Taste? 13.

A. \( \frac{3}{10} \) B. \( \frac{1}{2} \) C. \( \frac{3}{8} \) D. \( \frac{2}{5} \) Construye el diagrama de árbol para representar los posibles caminos que puede recorrer una bolita en una tabla de Galton con 5 niveles, es decir, con 5 filas de clavos: la primera con un clavo, la segunda con dos, y asi sucesivamente. Em uma urna, há 12 bolas de mesmo peso e tamanho, sendo 4 pretas, 4 vermelhas e 4 brancas. Se pegarmos 3 bolas aleatoriamente, uma de cada vez, não as devolvendo à urna, calcule a probabilidade de sair a combinaçāo na ordem mostrada a seguir. Daniel tem uma urna que contém 3 bolas verdes, 5 bolas vermelhas, 4 bolas pretas e 3 bolas brancas. Em una única retirada, a probabilidade de que ele tire uma bola verde ou preta é de (A) \( \frac{8}{15} \). (B) \( \frac{7}{15} \). (C) \( \frac{1}{5} \). (D) \( \frac{1}{3} \). Gustavo está jogando um jogo de tabuleiro com seus amigos. Ele lançará um dado simples, de 6 faces, e vencerá o jogo se obtiver um resultado maior do que 4 . Sendo assim, a probabilidade de Gustavo vencer o jogo é de (A) \( \frac{1}{4} \). (B) \( \frac{1}{2} \). (C) \( \frac{1}{3} \). (D) \( \frac{1}{5} \). Danielle comprou um pacote de balas sortidas, sabendo que há nele 5 balas de morango, 3 de uva e 2 de cereja. Escolhendo ao acaso uma dessas balas, a probabilidade de que seja de uva é de (A) \( 20 \% \). (B) \( 30 \% \). (C) \( 40 \% \) D \( 50 \% \)
