A bank gives each new customer a 4 digit code number which alllows the new customer to create their own password. The code number is assigned randomly from the digits 1,3,5,and 7. No digit is repeated. what is the probablity that the code number for a customer will begin at 7?

constant of proportionality = 3 and the equation is c = 3p.

step-by-step explanation:

c = kp   where c = amount of caffeine in mg., p = oz of pepsi and k is the constant of proportionality.

substituting the values given:

24 = 8k

k = 3.

the same value of k will be obtained if we substitute the other given values.
