Question: What is the effect of increasing the number of trees in a Random Forest?

Options:

1. It always increases the training time.
2. It can improve model accuracy but may lead to diminishing returns.
3. It decreases the model\'s interpretability.
4. It reduces the model\'s variance but increases bias.

Correct Answer: It can improve model accuracy but may lead to diminishing returns.

Solution:

Increasing the number of trees can improve model accuracy due to better averaging, but there are diminishing returns after a certain point.
