We either draw the ace first and then the king, or we draw the king first and then the ace
The probability is
2 ( 4/52) ( 4/51) = 32 / 2652 = 8 / 663
Dividing through by 2 we have
(∛3)^3 - (∛3)^2 =
3 - ∛9
mn = 2m + 4n rearrange as
mn - 4n = 2m
n ( m - 4) = 2m
n = 2m / [ m - 4 ]
When
m n
0 0
3 -6
5 10
6 6
8 4
12 3
2 -2
-4 1

(2/5)pi radians = 72°
So....the area of the circle must be 5*20 pi = 100 pi since 360° = 5 * 72°
Tacos........
Note that log27 3 = 1/3
So....this implies that x^(1/3) = 4
Cube both sides
x = 64
Let the side of B = 1......area of B = 1^2 = 1
Let the side of a = 1/2
Shaded area = (1/2) * (1/2)^2 = 1/8
Shaded area 1/8
__________ = _____ = 1 / 8 = 12.5%
Area of B 1
We have 2^3 = 8 possibilities
Only one of these is H-T-H
So.....the probability = 1 / 8
Let Mike's current age = M and Alison's = 2M
4 years ago we had that
2M - 4 = 3 (M - 4) simplify
2M - 4 = 3M - 12 add 12 to both sides, subtract 2M from both sides
8 = M
2M = 16 = Alison's age now
