4. Find the probability. A bag contains 9 red, 5 yellow, and 4 blue marbles. What is the probability of pulling out a blue marble, followed by a red marble, without replacing the blue marble first?

1. Em uma fábrica de potes de plastico, observou-se no controle de qualidade que 1 em cada 10 potes apresentava algum tipo de defeito. Qual a probabilidade de escolher um pote aleatoria- mente dessa fábrica e ele não possuir defeito algum?

Question A stack of cards contains six RED cards numbered \( 1,2,3,4,5,6 \), five BLUE cards numbered \( 1,2,3,4,5 \), and four GREEN cards numbered \( 1,2,3,4 \). If a single card is picked at random, what is the probability that the card has an ODD number? - Express your answer as a simplified Fraction Provide your answer below:

Question 2 A bag contains 4 red balls, 3 black balls, and 3 green balls. Two balls are randomly drawn from the bag one after the other with replacement. 2.1 Construct a tree diagram to represent all possible outcomes of drawing two balls in succession. Clearly label the branches with the corresponding probabilities.

Question A professor gives a surprise quiz with one multiple choice question. There are 4 answer possibilities: B, C, and D. What is the probability that you randomly guess and select the correct answer? Give your answer as a fraction.

There are 52 cards in a standard deck of cards, with four suites: hearts, clubs, diamonds and spades. Each suit has 13 cards: Ace, \( 2,3,4,5,6,7,8,9,10 \), Jack, Queen, King . Let event \( A \) be choosing a card with 7 out of a standard deck of cards. Identify the numbers of each of the following. Enter the probability as a fraction: Provide your answer below: There are \( \square \) cards in the sample space. There are \( \square \) cards in event A. \( \mathrm{P}(\mathrm{A})=\square \), is the probability that you choose a 7 out of the deck of cards.
