Answer:
5
Step-by-step explanation:
First off find how many bowls and vases combined
12 bowls and 8 vases therefore 20
to find 1/4 of a number divide by 4
therefore, 20/4 is 5
There are 12 face cards and 4 aces to choose from. For the first card, the probability of drawing a face is

. Then the probability of drawing an ace second is

.
So the probability of drawing these two particular cards in the given order is
5 and 6 both go into 30
4/5= 24/30
1/6= 5/30
24/30-5/30= 19/30
X equals 5 8/11 because if you simplify the equation you get 10 1/2=3 2/3x. divide and get the answer
1/2 base x height
That’s it
