Let's pretend I have a bag of 40 marbles. 19 marbles are red, 21 marbles are blue. If I randomly pick 5 marbles out of the bag, what is the probability that 3 of those 5 marbles are red?
Chronos said:Keep in mind that it makes a difference if you are looking for exactly 3 of 5, or at least 3 of 5.
The "Marbles in a Bag Probability Question" is a classic probability problem that involves drawing marbles from a bag at random and calculating the probability of certain outcomes.
The setup of the "Marbles in a Bag Probability Question" involves a bag filled with marbles of different colors. Each marble has an equal chance of being drawn from the bag. The question typically asks for the probability of drawing a certain number or combination of marbles of a specific color.
The formula for calculating probability in the "Marbles in a Bag Probability Question" is the number of desired outcomes divided by the total number of possible outcomes. For example, if the question asks for the probability of drawing a red marble out of a bag with 10 marbles, and 3 of them are red, the probability would be 3/10 or 0.3.
Yes, the "Marbles in a Bag Probability Question" can be solved using combinations or permutations, depending on the specific question. Combinations are used when the order of the marbles does not matter, while permutations are used when the order does matter.
The "Marbles in a Bag Probability Question" can be applied to many real-life scenarios, such as predicting the outcomes of games of chance, analyzing the results of surveys, and understanding the likelihood of certain events occurring. It is also commonly used in statistics and data analysis.
