Question 1177519
First, let's find the total number of customers: 59 + 70 + 78 + 77 + 94 + 64 = 442

**1. Probability of customer being at least 20 but no older than 50:**

* This includes the age groups: 20-30, 30-40, and 40-50.
* Number of customers in these groups: 70 + 78 + 77 = 225
* Probability = 225/442

**2. Probability of customer being either older than 60 or younger than 40:**

* This includes the age groups: Less than 20, 20-30, 30-40, and 60 or more.
* Number of customers in these groups: 59 + 70 + 78 + 64 = 271
* Probability = 271/442

**3. Probability of customer being at least 50:**

* This includes the age groups: 50-60 and 60 or more.
* Number of customers in these groups: 94 + 64 = 158
* Probability = 158/442

**Answers:**

* **At least 20 but no older than 50:** 225/442 
* **Older than 60 or younger than 40:** 271/442
* **At least 50:** 158/442
