Question

1. nadia owns 7 red shirts and 7 blue shirts. she randomly chooses a shirt for the day, and she gets a red shirt. at the end of the day, she puts it into the washing basket. 4a will this affect the chances of choosing a red shirt tomorrow? no a yes b

Explanation:

To determine if putting the red shirt in the washing basket affects the chance of choosing a red shirt tomorrow, we analyze the total number of shirts and the number of red shirts. Initially, there are \(7\) red shirts and \(7\) blue shirts, so a total of \(7 + 7=14\) shirts. After choosing a red shirt and putting it in the washing basket (not back with the other shirts), the number of red shirts available for tomorrow is \(7 - 1 = 6\), and the total number of shirts is \(14 - 1=13\). The probability of choosing a red shirt initially was \(\frac{7}{14}=\frac{1}{2}\), and after the change, it is \(\frac{6}{13}\), which is different. So this action affects the chances.

Answer:

B. Yes
