Answer:
1/12
Step-by-step explanation:
There are a total of 12 cards, each having one shape.
Assuming each card has a different shape, only 1 card will have a star on it.
Our new question is: what is the chance that Leah takes 1 specific card out of 12?
The answer: 1/12
As there is 1 star per 12 cards.
