Let's denote the number of red shoes drawn as \( x \).

The total number of shoes is \( 5 \) red + \( 4 \) green = \( 9 \) shoes.

The probability of drawing a red shoe is the number of red shoes drawn (\( x \)) divided by the total number of shoes (\( 9 \)).

So, the probability \( P \) of drawing a red shoe is given by:

\[ P = \frac{x}{9} \]

We are given that \( P = 0.2777777777777778 \), so we can set up the equation:

\[ 0.2777777777777778 = \frac{x}{9} \]

To solve for \( x \), we multiply both sides of the equation by \( 9 \):

\[ 9 \times 0.2777777777777778 = x \]

\[ x = 2.5 \]

However, since we cannot draw half a shoe, the number of red shoes drawn must be a whole number. The closest whole number to \( 2.5 \) is \( 2 \) or \( 3 \), but since \( 2.5 \) is exactly halfway between \( 2 \) and \( 3 \), and we are looking for the number of red shoes drawn that gives us the probability closest to \( 0.2777777777777778 \), we need to check which of these two values gives a probability closer to the given value.

For \( x = 2 \):
\[ P = \frac{2}{9} = 0.2222222222222222 \]

For \( x = 3 \):
\[ P = \frac{3}{9} = 0.3333333333333333 \]

The given probability \( 0.2777777777777778 \) is closer to \( \frac{2}{9} \) than to \( \frac{3}{9} \), so the number of red shoes drawn is \( 2 \).
빨간색 신발의 개수를 \( x \)로 표시해 보겠습니다.

총 신발 수는 빨간색 신발 5개 + 녹색 신발 4개 = 9개입니다.

빨간색 신발을 그릴 확률은 빨간색 신발을 그린 개수(\( x \))를 총 신발 수(\( 9 \))로 나눈 값입니다.

따라서 빨간색 신발을 그릴 확률 \( P \)는 다음과 같이 주어집니다:

\[ P = \frac{x}{9} \]

P = 0.2777777777777778 \)이 주어졌으므로 방정식을 설정할 수 있습니다:

\[ 0.2777777777777778 = \frac{x}{9} \]

x를 풀기 위해 방정식의 양쪽을 \( 9 \times로 곱합니다:

\[ 9 \times 0.2777777777777778 = x \]

\[ x = 2.5 \]

그러나 신발의 절반을 그릴 수 없으므로 그려진 빨간색 신발의 수는 정수가 되어야 합니다. 2.5에 가장 가까운 정수는 2 또는 3이지만, 2.5는 2와 3의 정확히 중간이므로 0.2777777777777778에 가장 가까운 확률을 주는 빨간색 신발의 개수를 구하므로 이 두 값 중 어느 것이 주어진 값에 더 가까운 확률을 주는지 확인해야 합니다.

x = 2의 경우
\[ P = \frac{2}{9} = 0.22222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222
