A keypad at the entrance of a building has 10 buttons labeled 0 through 9. What is the probability of a person correctly guessing a 9-digit entry code if they know that no digits repeat?

Answer:

the probability of a person correctly guessing a 9-digit entry code if they know that no digits repeat is 0.1

Step-by-step explanation:

We know that probability= number of required outcomes /number of all possible outcome.

From the given information;

the number of required outcome is guessing a 9-digit = 1 outcome

the number of all possible outcome = ¹⁰C₉ since there are 10 numbers and 9 number are to be selected.

Since there are only 9-digit that opens the lock;

the probability of a person correctly guessing a 9-digit entry code is

$P =\dfrac{1}{^{10}C_9}$

$P =\dfrac{1}{\dfrac{10!}{9!1!}}$

$P =\dfrac{1}{10}$

P = 0.1

Answer:

$-3m^{12}{n^{6} }$

Step-by-step explanation:

To begin simplifying this, we can first divide the coefficients, giving us:

$\frac{-3m^{5}n^{4} }{m^{-7} n^{-2} }$

We know that when dividing exponents, this means we need to subtract the exponent on the denominator from the numerator. This gives us:

$\frac{-3m^{5+7} n^{4+2} }{1}$

Now, simplifying this gets:

$-3m^{12}{n^{6} }$

Two diced are rolled. What is the probability that the sum of two numbers on the dice will be 4? 11/121/40

makkiz [27]

Each die has 6 possible outcomes (the numbers from 1 to 6).

If we roll two dices, the total number of outcomes is 6 * 6 = 36.

From these outcomes, the ones that have a sum of 4 are:

(1, 3), (2, 2) and (3, 1).

So, if we have 3 wanted outcomes from a total of 36, the probability is:

$P=\frac{3}{36}=\frac{1}{12}$

Therefore the correct option is the second one.
