## What is a factor tree diagram?

more A special diagram where we find the factors of a number, then the factors of those numbers, etc, until we can’t factor any more. The ends are all the prime factors of the original number.

## What is the tree method?

The classification tree method consists of two major steps:

- Identification of test relevant aspects (so called classifications) and their corresponding values (called classes) as well as.
- Combination of different classes from all classifications into test cases.

**Is 176 composite or prime?**

Prime Factorization of 176 Since it has a total of 5 prime factors, 176 is a composite number.

### What is a tree factor?

Factor trees are a way of expressing the factors of a number, specifically the prime factorization of a number. Each branch in the tree is split into factors. Once the factor at the end of the branch is a prime number, the only two factors are itself and one so the branch stops and we circle the number.

### What is the LCM of 20 and 25 and 30?

300

Answer: LCM of 20, 25, and 30 is 300.

**How did a tree diagram get its name?**

They get their name because these types of diagrams resemble the shape of a tree. The branches of a tree split off from one another, which then in turn have smaller branches. Just like a tree, tree diagrams branch out and can become quite intricate.

## Can a tree diagram branch out like a coin?

Just like a tree, tree diagrams branch out and can become quite intricate. If we toss a coin, assuming that the coin is fair, then heads and tails are equally likely to appear.

## Why do you multiply across the branches of a tree diagram?

We can think of this as . So this is why Joe said that you multiply across the branches of the tree diagram. “And” only means multiply if events are independent, that is, the outcome of one event does not affect the outcome of another. This is certainly true for our example, since flipping the coin has no impact on the outcome of the die throw.

**What do the fractions represent in a tree diagram?**

Each path represents a possible outcome, and the fractions indicate the probability of travelling along that branch. For each pair of branches the sum of the probabilities adds to 1.
