Answer:
There is a
probability that the correct password is found on the sixth try.
Step-by-step explanation:
We have n passwords, only 1 is correct.
So,
Since a password is put back with other, at each try, we have that:
The probability that a password is correct is 
The probability that a password is incorrect is
.
There are 6 tries.
We want the first five to be wrong. So each one of the first five tries has a probability of
. So, for the first five tries, the probability of getting the desired outcome is
.
We want to get it right at the sixth try. The probability of sixth try being correct is
.
So, the probability that the first five tries are wrong AND the sixth is correct is:

There is a
probability that the correct password is found on the sixth try.

No. A polynomial equation in one variablel ooks like P(x) = Q(x), where P and Q are polynomials.
Consider polynomial equations x^2 = 3 and x^2 = 1.
Obviously they have real solutions.
Subtract the two polynomial equations:
(x^2 - x^2) = (3 - 1)
0 = 2...
We get the polynomial equation 0 = 2. We call this a polynomial equation because single constants are also by definition polynomials.
Obviously 0 = 2 has no real solution.

Equation of a line

- Sub one set of points into equation

Answer:
8 shirts
Step-by-step explanation:
Given the equation a = 3b, where
a = the number of shirts Wanda has
b = the number of shirts Wanda's brother (Will) has
Hence if Wanda has 24 shirts then
24 = 3b
Divide both sides by 3
24/3 = b
b = 8 shirts
Will has 8 shirts.
