초코파이는 떡볶이를 매일 같은 방식으로만 먹다가 너무 질려버렸다.

그래서 네가지 방법을 찾았다.

1. 직접만들기

2. 튀기기(?)

3. 굽기(?)

4. 짜장떡볶이

이 네가지 방법 중 한개 이상을 선택할 때, 떡볶이의 경우의 수는?

이 중 두개 이상을 중복해서 짜장떡볶이를 굽거나 직접 짜장떡볶이를 튀기거나 이렇게 만들어도 된다.

단, 튀기기와 굽는 것은 둘다 할 순 없다.

2. 초코파이는 인터넷을 찾다가 라볶이라는 것이 있다는 것을 알았다.

집에 두 가지 종류의 라면이 있다.

이제 경우의 수는 얼마나 될까?

이 문제 어떠셨나요?

글쎄요
