In summary, simple probability is a measure of the likelihood of a certain event occurring, expressed as a fraction or decimal between 0 and 1. To calculate simple probability, you divide the number of favorable outcomes by the total number of possible outcomes. It differs from compound probability, which deals with multiple events or conditions and takes into account different probabilities. Simple probability is used in real-life situations such as predicting sports games or assessing risk. It cannot be greater than 1, as this would imply certainty which is not possible.

This looks like a homework problem. Please note that you must show some work before we can help you. Also, it is easier if you post the question in the thread, instead of linking to it, to enable people who want to help you to refer to the question quickly.

Hi there,

Sure, I would be happy to help you with your probability question. Based on the image you provided, it looks like you are trying to find the probability of selecting a red marble from a bag containing both red and blue marbles.

To solve this problem, we need to know the total number of marbles in the bag and the number of red marbles in the bag. From the image, we can see that there are 6 marbles in total and 3 of them are red. Therefore, the probability of selecting a red marble would be 3/6 or 1/2.

I hope this helps! Let me know if you have any other questions. Good luck!
 

1. What is simple probability?

Simple probability is a measure of the likelihood of a certain event occurring. It is typically expressed as a fraction or decimal between 0 and 1, where 0 represents impossibility and 1 represents certainty.

2. How do you calculate simple probability?

To calculate simple probability, you divide the number of favorable outcomes by the total number of possible outcomes. For example, if you roll a standard six-sided die, the probability of rolling a 3 would be 1/6, since there is only one way to roll a 3 out of six possible outcomes.

3. What is the difference between simple and compound probability?

Simple probability deals with a single event, while compound probability deals with multiple events or conditions. Simple probability is also based on equally likely outcomes, while compound probability takes into account the different probabilities of each event occurring.

4. How is simple probability used in real life?

Simple probability is useful in many real-life situations, such as predicting the outcome of a sports game, determining the chances of winning a lottery, or assessing the risk of certain events occurring.

5. Can simple probability be greater than 1?

No, simple probability cannot be greater than 1. This would imply that an event is certain to occur, which is not possible. Probability values greater than 1 are meaningless and do not represent a valid measure of likelihood.
