Probability 1st card is a diamond.....13 diamonds in the deck....13/52 reduces to 1/4
replace
probability 2nd card will be black....there are 26 black cards.....26/52 reduces to 1/2
replace
probability 3rd card is an ace....4 aces in the deck...4/52 reduces to 1/13
probability for all of that happening : 1/4 * 1/2 * 1/13 = 1/104 or 0.0096 or 0.96%
Estimation involves rounding
3/8 is closest to 4/8 which is 1/2, or 6/12
6/12 + 1/12 = 7/12
that is the estimated answer

Answer:
So, the correct option is A. x = 9, y = 14 , Sides are 11 and 20
Step-by-step explanation:
P.S - the exact question is -
As given in the question ,
Side AB = Side AD
⇒y - 3 = x + 2
⇒y - x = 2 + 3 = 5
⇒y - x = 5 .........(1)
Also, given
Side BC = Side CD
⇒2x + 2 = x + 11
⇒2x - x = 11 - 2
⇒x = 9
∴ equation (1) becomes
y - 9 = 5
⇒y = 5 + 9 = 14
⇒y = 14
∴ we get
x = 9, y = 14
Now,
as given ,
Side AB = y - 3
⇒ AB = 14 - 3 = 11
Side BC = 2x + 2
⇒ BC = 2(9) + 2 = 18 + 2 = 20
Side CD = x + 11
⇒ CD = 9 + 11 = 20
Side DA = x + 2
⇒DA = 9 + 2 = 11
∴ we get
The sides are 11 and 20
So,
The correct option is A. x = 9, y = 14 , Sides are 11 and 20
