Answer:
1/5525 ≈ 0.018%
Step-by-step explanation:
There are 4 kings in a standard deck of 52 cards.
The probability that the first card is a king is 4/52.
The probability that the second card is also a king is 3/51 (the first king isn't replaced, so there's one less king and one less card in the deck).
The probability that the third card is a king is 2/50.
The probability of choosing 3 king cards is therefore:
P = (4/52) (3/51) (2/50)
P = (1/13) (1/17) (1/25)
P = 1/5525
P ≈ 0.018%
 
        
             
        
        
        
Answer:
14: B. 40 C. 40 D. 100
Step-by-step explanation:
a triangle is 180 degrees adding all the angles. The triangle on the top is just a mirror for the bottom and since B and C are the same that equals 80 and when you subtract 80 from 180 you get 100 so that makes D 100. 
To double check just add 100+40+40=180
