Question 1170276
Let's break down this probability problem step by step.

**1. Calculate the Total Number of Items**

First, we need to find the total number of items purchased:

Total items = 26 (Kenneth Cole dresses) + 57 (Michael Kors dresses) + 20 (Vera Wang dresses) + 64 (Kenneth Cole jeans) + 73 (Michael Kors jeans) + 20 (Vera Wang jeans)
Total items = 26 + 57 + 20 + 64 + 73 + 20 = 260

**2. Calculate the Number of Items Purchased from Michael Kors or Vera Wang**

Next, we calculate the number of items purchased from Michael Kors or Vera Wang:

Michael Kors items = 57 (dresses) + 73 (jeans) = 130
Vera Wang items = 20 (dresses) + 20 (jeans) = 40
Michael Kors or Vera Wang items = 130 + 40 = 170

**3. Calculate the Probability**

Finally, we calculate the probability by dividing the number of items purchased from Michael Kors or Vera Wang by the total number of items:

Probability = (Number of Michael Kors or Vera Wang items) / (Total items)
Probability = 170 / 260

**4. Reduce the Fraction**

Now, we reduce the fraction to its simplest form. Both 170 and 260 are divisible by 10:

170 / 10 = 17
260 / 10 = 26

So the fraction is 17/26. This fraction cannot be further reduced.

**Answer:**

The probability that the item selected was purchased from Michael Kors or Vera Wang is 17/26.
