Answer:
Prob = 1.96%
Step-by-step explanation:
p = pennies
t = total
total Prob = Prob1*Prob2
P1 = # pennies/total
P2 = new #/new total
total Prob = (p/t)*((p-1)/(t-1))
I believe your answer should be $0.95
Of course, I could be wrong, and I apologise if I am.
6 4

4 3
_____
1 0 7
______
3 + 4 = 7 Put down the 7.
6 + 4 = 10 Put down the 0 first, and then 1 is left. Put down the 1 also to the extreme left.
So the answer is 107
-px+r=-8x-2 add 8x to both sides
8x-px+r=-2 subtract r from both sides
8x-px=-r-2 factor left side
x(8-p)=-r-2 divide both sides by (8-p)
x=(-r-2)/(8-p) multiply right side by -1/-1
x=(r+2)/(p-8)
