Problem Analysis

The problem states that there is a stack of 6 balls of different colors: red, yellow, green, blue, pink, and black. Sveta takes out one ball at a time from the stack without looking at it. If the ball is not red, she puts it aside and continues taking out balls until she gets a red one. The question is: what is the maximum number of attempts Sveta needs to make in order to draw a red ball from the stack?

Solution

To find the maximum number of attempts Sveta needs to make to draw a red ball from the stack, we need to consider the worst-case scenario. In this case, the worst-case scenario is that the red ball is the last ball in the stack.

Let's analyze the process step by step:

1. Sveta takes out the first ball from the stack. There are 6 balls in total, so there are 5 balls left in the stack. 2. If the first ball is not red, Sveta puts it aside and continues to the next step. Otherwise, she has already found the red ball and the process ends. 3. Sveta takes out the second ball from the stack. There are 5 balls left in the stack. 4. If the second ball is not red, Sveta puts it aside and continues to the next step. Otherwise, she has found the red ball and the process ends. 5. Sveta continues this process until she either finds the red ball or reaches the last ball in the stack.

In the worst-case scenario, the red ball is the last ball in the stack. Therefore, Sveta needs to go through all the other balls before finding the red one. Since there are 5 balls other than the red ball, Sveta needs to make a maximum of 5 attempts to draw the red ball from the stack.

Answer

The maximum number of attempts Sveta needs to make in order to draw a red ball from the stack is 5.
