Answer:
1/4
Explanation:
You want the probability that a random choice from a menu of 9 items, including 3 vegetables, is a vegetable after one vegetable has already been chosen. The second choice is different from the first.
Menu
After choosing one vegetable, the available different items remaining on the menu are 2 vegetables among a total of 8 items.
The probability that the second random choice will be a vegetable is ...
(2 vegetables)/(8 items) = 2/8 = 1/4
The probability that the second choice is also a vegetable is 1/4.

Additional comment
Since the choices must be different, the first choice is essentially removed from the menu. Since we're only concerned with the second choice, we don't need to consider the probability that the first choice was a vegetable.
