Question 1171468
Let's break this problem down step-by-step.

**1. Organize the Data**

* Total Male Workers: 360
* Total Female Workers: 640
* Total Workers: 360 + 640 = 1000
* Male Workers Earning < RM2000: 100
* Male Workers Earning >= RM2000: 360 - 100 = 260
* Female Workers Earning >= RM2000: 170
* Female Workers Earning < RM2000: 640 - 170 = 470

**a. Probability of Only One Worker Receiving RM2000 Bonus (Two Randomly Chosen Workers)**

We need to consider two cases:

* Case 1: The first worker gets the RM2000 bonus, and the second worker doesn't.
* Case 2: The first worker doesn't get the RM2000 bonus, and the second worker does.

* **Case 1:**
    * Probability of a worker getting RM2000 bonus: (100 + 470) / 1000 = 570 / 1000 = 0.57
    * Probability of a worker NOT getting RM2000 bonus: (260 + 170) / 1000 = 430 / 1000 = 0.43
    * Probability (Case 1): (570/1000) * (430/999)

* **Case 2:**
    * Probability of a worker NOT getting RM2000 bonus: 430 / 1000 = 0.43
    * Probability of a worker getting RM2000 bonus: 570 / 999
    * Probability (Case 2): (430/1000) * (570/999)

* **Total Probability:**
    * (570/1000) * (430/999) + (430/1000) * (570/999) = 2 * (570/1000) * (430/999)
    * = 2 * (0.57) * (0.43043)
    * = 0.490526

**b. Probability of Only One Worker Receiving RM2000 Bonus (One Male, One Female)**

We again have two cases:

* Case 1: The male worker gets the RM2000 bonus, and the female worker doesn't.
* Case 2: The male worker doesn't get the RM2000 bonus, and the female worker does.

* **Case 1:**
    * Probability of a male worker getting RM2000 bonus: 100 / 360
    * Probability of a female worker NOT getting RM2000 bonus: 170 / 640
    * Probability (Case 1): (100 / 360) * (170 / 640)

* **Case 2:**
    * Probability of a male worker NOT getting RM2000 bonus: 260 / 360
    * Probability of a female worker getting RM2000 bonus: 470 / 640
    * Probability (Case 2): (260 / 360) * (470 / 640)

* **Total Probability:**
    * (100 / 360) * (170 / 640) + (260 / 360) * (470 / 640)
    * = (17000 / 230400) + (122200 / 230400)
    * = 139200 / 230400
    * = 0.6041666666666667
    * Approximately 0.6042
