Question

In your own words the fundamental counting principle and explain why it’s useful in probability

Answer 1

The fundamental counting principle states that if there are p ways to do one thing, and q ways to do another thing, then there are $p\times q$  ways to do both things.

Probability requires the favourable and total possible outcomes.

Counting favourable and total outcomes is required for finding the probability .

Thus, the fundamental counting principle is important in calculating the probability.
