- Hi, welcome to this question right here. So what happened is, I actually did the answer already. But let's just go through the question and see what happens. Right? 
So Ken over here flips a coin. And we know that there's only head and tail on the coin. Right? So basically what happened is at the very beginning you had to get a head or you had to get a tail. Okay? Then you can go to a bag the contents. Find different marbles, each with different colors. And we&apos;ve got the green, the blue, red, orange and the yellow. Okay? So what happened is after you do this, you flip the head. There's a possibly that you can get a green, blue, red, orange or yellow. Right? Same thing with the tail. Okay? 
Once you flipped the tail. You might get a green, blue, red, orange or the yellow. Right? So the total sample space you're going to have for this question is just going to be these guys over here. Total of 10. Okay? We&apos;ve got a head and green, head and blue, head and red, head and orange, head and yellow. And of course got a tail and a green, tail/blue, tail/red, tail/orange and tail and yellow. Okay? So this is the tree diagram for this sample space. Okay? 
Thanks for watching.

Building tree diagrams for compound probability events

Intro to probability with tree diagrams and combined events

Tables and tree diagrams are useful tools to calculate probabilities. With them, you can list all the possible outcomes of an event (<a href='[[glossary.html|{"keyword":"Sample Space"}]]'>sample space</a>) in a clear and easy to understand way. Therefore, we can determine the probabilities of events effectively.
