In summary, the conversation discusses a problem with a question involving placing three coins on a grid. They suggest approaching the problem by finding the probability of placing the coins on the diagonals, and then discuss the process of placing the coins one at a time and determining the options for each placement.

Hello, I have a problem with this question
http://www.icefusionf1.com/prob.png
My thoughts:
I think it is better to work out the probability of the 3 coins being placed on the diagonals.

Please help?

No. :frown:

In problems like this, generally start "the first one …, then the second one …, then …"

In this case, place the thre coins one at a time.

The first coin can go anywhere - no restriction.

With the first coin fixed, how many options are there for the second coin?

Then, with both the first and second coins fixed, how many options are there for the third coin? :smile:
 

1. What is a probability problem?

A probability problem is a question or situation that involves calculating the likelihood of a certain event or outcome occurring. This can involve using mathematical formulas and concepts such as permutations, combinations, and probability distributions.

2. How can I solve a probability problem?

The first step to solving a probability problem is to clearly define the question and identify the given information. Then, you can apply relevant formulas and concepts to calculate the probability. It is important to show all your work and use proper notation to arrive at the correct answer.

3. What are some common strategies for solving a probability problem?

Some common strategies for solving a probability problem include using tree diagrams, tables, and Venn diagrams to organize the given information and visualize the problem. Additionally, understanding the difference between independent and dependent events, and knowing when to use the addition or multiplication rule can also be helpful.

4. What are some common mistakes to avoid when solving a probability problem?

One common mistake to avoid when solving a probability problem is using incorrect formulas or not understanding the problem correctly. It is important to carefully read and interpret the question and double check your calculations. Another mistake to avoid is assuming that events are independent when they are actually dependent, or vice versa.

5. Where can I get help with solving a probability problem?

You can get help with solving a probability problem from various sources such as textbooks, online tutorials, and math forums. You can also seek assistance from a math tutor or teacher who can provide personalized guidance and feedback on your problem-solving approach.
