A store has several cans of blue paint and several cans of red paint

­(1) The number of cans of red paint in the store is equal to the number of cans of blue paint in the store.
We cann't reach out to a certain number of cans based on this information. So, we can eliminate A & D answer choice from the question. Now, we are left with BCE.

(2) The store has a total of 24 cans of paint in stock.
This information does not mention specific number of cans with the specific paints, blue & red. Certainly, B is not our answer.

Now, if we combine the above stated information together, we get, 12 numbers of cans with blue paints & 12 numbers of cans with red paints, total 24 numbers of cans.

Probability= number of ways 2 cans can be selected from 12 cans with red paints, 12C2 / number of ways 2 cans can be selected from total 24 number of cans, 24C2. So, the answer is C.  ­
