It should be 24 because <span>Pick 3 aces: 4C3 = 4 ways
Pick 2 kings: 4C2 = 6 ways
# of full-house hands: 4*6 = 24</span>
The Lagrangian for this function and the given constraints is

which has partial derivatives (set equal to 0) satisfying

This is a fairly standard linear system. Solving yields Lagrange multipliers of

and

, and at the same time we find only one critical point at

.
Check the Hessian for

, given by


is positive definite, since

for any vector

, which means

attains a minimum value of

at

. There is no maximum over the given constraints.
Yes it is a right triangle
4(2a+3) = 8a+ 12
This represents the distribution property because it multiplies everything in the parentheses. 4 X 2a = 8a 4X3=12
Answer:
(30/40)*(29/39) = 29/52 =~ 0.55769
Step-by-step explanation:
The probability is calculated assuming the cars were chosen without replacement .
