Answer:

Step-by-step explanation:

f(-9+h)= (-9+h)² = h²-18h+81

f(-9+h)-f(-9)=h²-18h+81 -81 because : f(-9) = (-9)² = 81

f(-9+h)-f(-9)=h²-18h

(f(-9+h)-f(-9))/h=(h²-18h)/h = h(h-18)/h =h-18

lim  (f(-9+h)-f(-9))/h = lim(h-18= - 18

h→0                             h→0

A safe has a 4-digit lock code that does not include zero as a digit and no digit is repeated. What is the probability of a lock
Elenna [48]
Probability of lock code with all even digits =  (4/9) ^ 4 =  256/6561 = 0.039 

So probabiilty of lock without all even digits = 1 - 0.039  =  0..961.
