This process is repeated 40 times. The graph summarizes the results. Which statement about the experimental and theoretical probability of this experiment is true? A The theoretical probability of ... Oct 04, 2020 · Thus the probability of choosing the second red marble is 4/11. The probability of choosing a green marble in these 10 remaining marbles is 3/10. So P(A) = 5/12 * 4/11 * 3/10 B: The probability of consecutively choosing a red and two blue marbles with replacement As there are 5 red marbles, the probability of choosing a red marble between 12 ... The chances of drawing 2 blue marbles is 1/10. P(A) means "Probability Of Event A" In our marbles example Event A is "get a Blue Marble first" with a probability of 2/5: P(A) = 2/5 And Event B is "get a Blue Marble second" ... but for that we have 2 choices: • If we got a Blue Marble first the...The bag still contains four blue and three white marbles.
