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.
Answer:
7h+3=-11?
then h=-11-3 divided by 7
Step-by-step explanation:
Answer:
Apply the formula for sum of cubes:
Therefore:
You multiply the exponent
Remember to MULTIPLY exponents (not add them) when you are raising a power to a power. In this case, (−3x3y2)4 = (−3)4(x3)4(y2)4 = −34 · x3·4 · y2·4.
Answer:
3(2) x 11 = 99
2(2) x 3(2) = 36
3(2) x 5 = 45
5(1) = 5
2(3) x 3 = 24
