A deck as 52 cards and 4 kings
p(king) = 4/52 =1/13
[Getting l as in the letter “L” and not the letter “i” right?]
P(l) = 1/10
P(king and I) = 1/13 x 1/10 = 1/130
K=-1 or k=5
either quantity could equal zero, so put each quantity equal to zero and solve for k.
hope this helps :)

Answer:
C
Step-by-step explanation:
You have 2 totals so the number of males + females = 127 so x + y = 127
Then there are 23 more males than females, it did not say 23 times more so B is out, so the female number + 23 = male number so y + 23 = x
Therefore letter C is the answer.
