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))
T and 3t are like terms. 8 is by itself.
Answer
-12
Step-by-step explanation:
Y-y over X-x, so -7-(-19) over -2-(1)
Don't forget (X,Y) and (x,y) positions! Very important for algebra!
