C
1. Substitute the 8 for g
2. Divide it by 2
3.Then add by 3
<span>If we add these two equations together, we can quickly follow the system via the elimination method as the y-terms cancel out.
Doing so results in 6x= -30, so x = -5. Plug this in and solve for y.
2*(-5) + 3y = -7, -10 + 3y = -7, 3y = 3, y = 1.
The solution is therefore (-5,1).</span>

.......................
When you have 3 choices for each of 6 spins, the number of possible "words" is
3^6 = 729
The number of permutations of 6 things that are 3 groups of 2 is
6!/(2!×2!×2!) = 720/8 = 90
A) The probability of a word containing two of each of the letters is 90/729 = 10/81
The number of permutations of 6 things from two groups of different sizes is
(2 and 4) : 6!/(2!×4!) = 15
(3 and 3) : 6!/(3!×3!) = 20
(4 and 2) : 15
(5 and 1) : 6
(6 and 0) : 1
B) The number of ways there can be at least 2 "a"s and no "b"s is
15 + 20 + 15 + 6 + 1 = 57
The probability of a word containing at least 2 "a"s and no "b"s is 57/729 = 19/243.
